Wu Sir is worried about Lap Man and calls him repeatedly. However, Lap Man is unreachable. Wu Sir checks with Pak Kiu if he has seen Lap Man, but Pak Kiu denies. Wu Sir asks Pak Kiu to send a team to look for Lap Man.
Yuk Bo finds Fa Si Lai at home. Fa Si Lai says she feels unwell and has problems sleeping at night. She even dreams of Sam Jie. Yuk Bo lies to Fa Si Lai and tells her that Sam Jie called home in the morning. Pak Kiu was the one who answered the phone. Fa Si Lai felt better after knowing that Sam Jie had called home. When Pak Kiu returns, Fa Si Lai asked him about the call. Pak Kiu did not know about the white lie so he could not answer Fa Si Lai. Fa Si Lai caught Pak Kiu and Yuk Bo lying and knows that something has happened to Sam Jie. She forced the truth out of them.
Fa Si Lai goes to Hau Ko's house to beg him for information on Sam Jie. Hau Ko tells them that he no longer loves Sam Jie so they had broken up. He doesn't know her whereabouts. Even Yau Yau asked Hau Ko to tell them where Sam Jie is but Hau Ko insist he doesn't know. Yau Yau is upset with Hau Ko and storms off to her room.
Lap Man uses his identity as "Lucky Prince" to cheer Yau Yau up via her blog. Yau Yau says Sam Jie once told her that it doesn't matter if a person is good or bad. As long as that person treats her well, then that person is a good person. However, now that her "good" father has hurt her beloved Sam Jie, she doesn't know what to think of him anymore.
Hau Ko tells Lap Man that he has an assignment for him, and asks Lap Man to be on standby. This assignment is once again another test set up by Hau Ko to test Lap Man's loyalty. Hau Ko asks Lap Man to carry drugs and at the same time he tipped off the police. While Lap Man was taking the packet of drugs, he was cornered by the police. He tries to escape inside a building, but he has no way out. The only way is up. The police continues to pursue Lap Man.
Chuen Suk managed to follow Lap Man all the way up to the rooftop. Lap Man leap from the rooftop to the rooftop of the next building. Chuen Suk follow suit but could not make it and slipped. He held on to some cables but the cables kept slipping so Lap Man quickly grabbed the cables to help Chuen Suk. Lap Man then realised that his identity has been compromised as Hau Ko and Chung were watching him from another building. Hau Ko is convinced that Lap Man is an undercover cop!
Wu Sir orders Pak Kiu and Chuen Suk to arrest Lap Man. He says Lap Man has gone overboard with his actions and wants him arrested. Pak Kiu and Chuen Suk tried to reason with Wu Sir and tells him to investigate thoroughly first, but Wu Sir insists on arresting Lap Man.
Lap Man is now holding on to the packet of drugs that he carried earlier. Wu Sir calls him and orders him to return to the safe house immediately and hand over the drugs to the police. On the other hand, Chung calls Lap Man and tells him to bring the drugs and meet Hau Ko. Lap Man has to decide which side he is going to listen to. He flips a coin to decide.
Hau Ko tells Yau Yau that Lap Man will not be coming home anymore as he is an undercover cop. Yau Yau was shocked that Hau Ko has discovered Lap Man's identity. Hau Ko was even more enraged that Yau Yau has concealed this important piece of information from him. He tells Yau Yau that Lap Man does not love her and only pretends to be with her to get close to him. Yau Yau tells Hau Ko that he has changed and is now a terrifying, cold-hearted person. She does not know who he is anymore.
Yau Yau tries to tell Lap Man that Hau Ko is looking for him. However, Hau Ko heard her talking on the phone and interrupt her call. He pulls a gun at Yau Yau. Lap Man hears Yau Yau screaming on the phone and is worried. Even though he knows that his life is at risk, he still goes to the house to look for Yau Yau.
Hau Ko sarcastically praise Lap Man for being brave. He dares to meet Hau Ko even though he knows that his identity has been revealed. Lap Man says he is prepared to die, but wants Hau Ko to spare Yau Yau as she is innocent. Hau Ko wants Lap Man to die for Yau Yau and pulls the trigger on him. But the gun was blank. He spared Lap Man his life for Yau Yau's sake. It was only a test to see if Lap Man's love for Yau Yau is real.
Hau Ko and Lap Man have a argument about what is right and what is wrong. Hau Ko says that triads exist first before police. He convinces Lap Man to work with him in the triads and leave the police force. Hau Ko tells him that together they can achieve great things. Hau Ko tells Lap Man that he has gone overboard being an undercover, the police force would not want him anymore.
Wu Sir calls for a meeting with his staff in OCTB and arranges a new task for them. He wants them to target the new triad leader in Chun Hing - Lap Man! He orders them to arrest Lap Man and get enough evidance to charge him in court.
Pak Kiu looks for Wu Sir to ask Wu Sir the rationale in arresting Lap Man. Wu Sir says Lap Man is beyond control now and lacks discipline. He is not sure if Lap Man has defected to the "bad" side. Wu Sir tells Pak Kiu that by arresting Lap Man, only they can find out from him the exact situation.
Lap Man's status as an undercover cop is known by everyone in Chun Hing. All the leaders are hunting for him. At the same time, the police is also looking for him. Lap Man now has no where to escape as he is wanted by both the police and the triads. Lap Man runs to Hau Ko and tells him that he wants to follow Hau Ko. Hau Ko welcomes him back into Chun Hing.
Chiu Sir visits Fa Si Lai at Oi Sam Ook. He notices that Oi Sam Ook's electricity bill is extremely high. He offers to help Fa Si Lai check the main switch. Fa Si Lai asks Chiu Sir to help her lock up the place as she is rushing to the hospital to check on Pak Kiu (who was injured when he tried to arrest Lap Man). While checking the main switch, Chiu Sir discovers the drug factory. One of the workers make Chiu Sir unconscious and deliver his body to Hau Ko. Hau Ko tells Lap Man and Chung that "only dead people can keep secrets". When Chung was going to shoot Chiu Sir, Lap Man offer to do it instead. He intentionally shoot to the side of Chiu Sir's heart and tells Chiu Sir to hang on!
Episode 30 *Ends*
From a conversation with Fa Si Lai, Pak Kiu is able to figure out that Hau Ko has set up the drug production factory at Oi Sam Ook. Pak Kiu was about to inform Wu Sir the latest development when he receives an SMS from Lap Man. Pak Kiu gather all his staff for an operation to arrest Hau Ko at Oi Sam Ook.
Pak Kiu made all necessary arrangements to corner Hau Ko at Oi Sam Ook. Hau Ko appears at the drug factory with Lap Man, Chung and another worker. When they were about to enter into the drug making area, Pak Kiu reveals himself. Upon further checking of the place, he discovered that the place is empty! The whole area has been cleaned and cleared. Lap Man tricked Pak Kiu! Hau Ko now believes that Lap Man is 100% on his side.
Wu Sir gave Pak Kiu a dressing down for going ahead with the operation without getting his permission. Pak Kiu admits that Wu Sir will not give him the green light as he lacks storng evidence, thus he decided to proceed without informing Wu Sir. Wu Sir tells him that the police force is all about discipline and he cannot act as he pleases.
Hau Ko praises Lap Man for alerting them about the police visit. Lap Man also suggests to Hau Ko that they should re-use the drug production factory in Oi Sam Ook. He reasons that the police would not guess that they would actually re-use the kitchen. Chung agrees with Lap Man.
Fa Si Lai goes to Hau Ko's house again. She begs Yau Yau to help her. She tells Yau Yau that Hau Ko causes Pak Kiu to be investigated and Chiu Sir is hanging on life support at the hospital. Yau Yau says she is unaware of Hau Ko's actions. When Hau Ko appears, Fa Si Lai kneels and begs him to tell her where Sam Jie is and to let Pak Kiu off the hook.
After Fa Si Lai left, Yau Yau tells Hau Ko to let Fa Si Lai knows where Sam Jie's body is. Yau Yau says Sam Jie is like family to her and loves her a lot. Yau Yau says if Hau Ko really did kill Sam Jie, then he should get the justified punishement for his actions. Hau Ko asks her if she wants to see him back in prison again. Yau Yau says YES! She says no matter how long Hau ko will be imprisoned, Sam Jie will never live again. Lap Man tries to console Yau Yau. Yau Yau says previously she turned a blind eye to Hau Ko's actions as she knows that he loves her. However, now that she knows that Hau Ko killed Sam Jie and hurt so many people, she could no longer pretend that Hau Ko is a "good" person.
Lap Man persuades Yau Yau to take over Oi Sam Ook. He tells Yau Yau that Sam Jie has put in so much effort into Oi Sam Ook and it would be a waste to shut it down. He says Sam Jie will be very happy to know that Yau Yau is taking over. Yau Yau agrees to take over and continue Sam Jie's efforts.
Hau Ko tells Lap Man that there will be new drugs arriving. Chung says the drug factory has been re-set up and can be used anytime. However he cautions that since Oi sam Ook is no longer in operation, they have to be careful. Lap Man says he has found a new proprietor for Oi Sam Ook - Yau Yau! He explains that with Yau Yau handling the restaurant, the police will be fooled. They will never imagined that Hau Ko will put his own daughter at risk. Hau Ko agrees and says Lap Man did well. He says one has to be evil and not let emotions cloud them to be successful.
Pak Kiu vists Chiu Sir at the hospital. He then receives a message from Chiu Sir's number saying "meet at the usual place". He was puzzled.
Lap Man brings the newly arrived drugs to the drug factory. Upon entering the drug factory, his handphone has been confiscated and kept in a drawer. This is to prevent anyone on the inside from communicating with those on the outside. The drugmaker discovered that the drugs are problematic. They contain foreign elements and could not be processed. Chung calls Hau Ko to the factory. Suddenly, they hear some noise from outside (Oi Sam Ook's kitchen). Rightfully, there shouldn't be anyone working in the restaurant. Lap Man says only Yau Yau has the keys and it could possibly be her. Hau Ko calls Yau Yau and they can hear her phone ringing. So it's confirmed that Yau Yau is in Oi Sam Ook.
Lap Man suggests that they quickly rescue the problematic drugs and only leave after Yau Yau has left. Chung disagrees, saying that Hau Ko seldom visit the factory. Why is it that during his current visit there are so many problems. Chung says something is not right and they decide to flee from the backdoor. However, the backdoor cannot be opened. The lock has been tempered with and the keyhole is blocked. Hau Ko pulls out his gun and asks among them who has betrayed the team. Everyone present pleads their innocence. Hau Ko tells them to cut open the lock.
Lap Man's Flashback
Lap Man has planned a trap to arrest Hau Ko. Earlier, he stuffed glue into the key holes of the backdoor at the drug factory. He then used Chiu Sir's mobile (which he took before he fired a shot at Chiu Sir) to send a text message to Pak Kiu, telling him to "meet at the usual place". Pak Kiu goes to the abandoned house to meet Lap Man. Lap Man tells him that he was the one who shot Chiu Sir. He explains that if Chung were to fire that shot, Chiu Sir would definitely be dead.
Pak Kiu demands an explanation from Lap Man about the botched arrest attempt on Hau Ko. Lap Man tells Pak Kiu that he has to put up the show to re-gain Hau Ko's complete trust. Lap Man tells Pak Kiu that Oi Sam Ook is still the drug factory and asks Pak Kiu to inform Wu Sir. Lap Man says he will temper with the drugs so that Hau Ko will show up at the factory. Lap Man will try to prolong the time Hau Ko stays at the factory so that the police will have enough time to show up. He also tells Pak Kiu that he will not have access to his phone the moment he enters the factory. Lap Man asks Pak Kiu to trust him as this is the only one chance they have to arrest Hau Ko!
Lap Man explains that he would use Yau Yau to prolong Hau Ko's stay in the factory. He will ask Yau Yau to meet him at Oi Sam Ook, so they could discuss about her relationship with Hau Ko. Yau Yau agrees as she does not want carry on hating her father.
Lap Man's Flashback ends
Hau Ko's worker is still trying to break open the backdoor so that they could escape. Yau Yau is cooking in the kitchen when the police arrives. Wu Sir tasked Pak Kiu to bring Yau Yau to a safe place. Wu Sir leads the team and they tries to break open the door to the drug making area, while at the same time the backdoor is opened. Chung tells Lap Man to protect Hau Ko and escape first while he fends off the police. Wu Sir manages to shoot Chung. Lap Man guides Hau Ko to escape.
Lap Man and Hau Ko escaped via the back alley. Hau Ko stopped for a moment to think. He then realised that Lap pMan is the one who tipped off the police. He fires at Lap Man, but Lap Man narrowly missed the shot. Pak Kiu who packed off Yau Yau in a taxi to go home, heard the shot and rushed over to check. Yau Yau also heard the shot in the taxi. Lap Man and Hau Ko struggles for Hau Ko's gun. Hau Ko accuses Lap Man of betraying him, but Lap Man tells him that he is wrong. Lap Man was NEVER his man to begin with! He has one aim which is to arrest Hau Ko.
Hau Ko and Lap Man fired shots at one another. Hau Ko fired a shot which hit Lap Man's right wrist. Wu Sir sends Chuen Suk and another officer to check on Lap Man. Hau Ko fired another shot at Lap Man's leg. Pak Kiu appears on the scene. Hau Ko then changed his target and fires at Pak Kiu. Pak Kiu picked up Lap Man's gun and aimed at Hau Ko. Hau Ko challenged him to fire it and called him a coward. Hau Ko fired at Pak Kiu and missed. It turned out that was the last bullet in his gun, so he flee from the spot. At the same time, Chuen Suk arrived.
Hau Ko runs out to the main street and sees Yau Yau in a taxi. She stopped the taxi and tells Hau Ko to quickly get on. Hau Ko hesitates. He is convinced that Yau Yau hates him more than she loves him and would never want to help him. He refused to get on and runs across the street. An oncoming car could not brake on time and hit Hau Ko. The driver and passengers in the car are all high on drugs!
Hau Ko has been arrested. Pak Kiu and Lap Man visit Lee Sir's (Pak Kiu's father) grave. Lap Man leaves his whistle (silver award from PTS) at Lee Sir's grave. Without a word to Pak Kiu, he walks away. Pak Kiu follows after Lap Man and asks him if he is really considering leaving the police force. Lap Man says he acts rashly and it is valid that Wu Sir had given up on him. Pak Kiu tells him that Wu Sir or the police force had never given up on him. It was La Ba (his friend and Yau Yau's former housemate) who was the one who spreads that Lap Man is an undercover cop.
Chiu Sir has woken up from his coma. He was questioned by the police if he could recognise his attackers. He claims that he was blindfolded, so he could not identify anyone.
Yau Yau visits Hau Ko in prison. The prison authorities tells her that Hau Ko attempts to commit suicide in prison. Yau Yau tells Hau Ko that he owes her too much, and has to repay his debts to her. She asks him to promise her that he will stay alive. She tells him that she will always be his daughter, and he her father. Yau Yau managed to persuade Hau ko to reveal where Sam Jie was burried. Fa Si Lai is happy that they are finally able to locate her body and she has a final resting place. Yuk Bo offers Yau Yau a place in their home but Yau Yau says that she will be travelling to clear her mind.
Lap Man visits the tree which he shares with Yau Yau and discover a note for him. The note is from Yau Yau. Yau Yau says that she has never blamed him for taking advantage of her to get close to Hau Ko, as their relationship from the beginning was already based on pretence. It started with her being a pirated DVD seller prentending to be a Princess on her blog while Lap Man is the Lucky Prince who left her comments, but he pretends otherwise. Then they pretend to date, for the sake of her blog entry, and then subsequently they actually dated. She also pretends that Lap Man is not an undercover cop, while Lap Man pretend that he never used Yau Yau to get close to Hau Ko. Yau Yau writes in the note that she could no longer keep track on who is pretending while who isn't.
She tells Lap Man that she truly believes that he had loved her once. He also brings her gifts - helping her to reconcile with Hau Ko, making her a real "Princess", who has a real family and loved by all. However, Yau Yau admits that too much has happened and they could no longer be together but she will always cherish him.
Lap Man carved a reply on the tree trunk for Yau Yau. The message reads, "You are the one I love most. Regardless of time, I will always wait for you. And earn your fogiveness."
Chiu Sir resumes duty and has switched to be a driver for EU. Yuk Bo has matured and is now an ICPC for her EU team. Lap Man reports for duty and is assigned to Pak Kiu's OCTB team.
