CHI KONG was being attacked on the way he accompanied WING KIT whom was shot and in a coma. Before he was unconscious, he spoke out a word `PASS' which became the only clue. KONG did not have enough evidence but let FOOK SIN go. YING got the password successfully. Though SIN had damaged the computer record, YING still could charge him because of her intelligence.
On the spot, MAN found KWAN and LAN. KONG also got the way out and everybody could escape. MAN failed to get in again and save PING. At last, the firemen saved her.
Everyone was late for lesson and very untidy. POK was very angry and punished them. During the outdoor training, MAN again played tricks on FAI who deliberately threw a red ball far away. FAI insisted to get it and won. POK was disappointed after recognizing most of them ate canned food.
POK's training was very harsh. Most of the trainees were being blamed and felt depressed. PING always took care of SHAN in order to get a favorable impression. FAI admired KIT's elegance very much and MAN also admitted that he liked SHAN.
After a long chase, KONG caught TAK. TAK had used his identity of being a Thai Chinese to travel between Hong Kong and Thailand and deposited money into Thailand bank. With sufficient evidence, he was sent to prison.
FAI supported SHAN and was scolded by POK. FAI and SHAN decided to resign while MAN and others dissuaded them from doing so. In fact, it was MAN who wrote anonymous letter. At the same time, POK also realized MAN spread out the rumour. MAN understood that he had made troubles and promised to clarify everything. POK asked SHAN and FAI to stay.
At last, YUEN was brought under control and admitted that he had copied the draw but it didn't affect the result.
KONG convinced MING not to have any deal with the Agent. Although MING claimed that he would not be moved, KONG was uneasy. He and MUI went to examine the flat and recognized that there was somebody died before. YUK was dismissed by YEE. If MING did not buy the flat, he would lose the deposit.
After realizing TUNG had come to the villa, KWONG arranged YEE to leave. TUNG thought that he might be over-suspicious and continued to trust YEE.
TUNG was mad. He grasped YEE with a knife and confronted with others. KONG deliberately slowed up and suggested MAN to approach him. TUNG got crazy suddenly. MAN and others caught TUNG and KWONG finally.
MAN eventually returned the car to BROTHER B whom admired him very much. BROTHER B assigned him to work in his karaoke bar with great responsibility.
YING met her ex-boyfriend KEI but she pretended as usual which made KEI felt unpleasant. YING was filled with deep emotion when she remembered herself being abandoned by KEI in the past. She determined never to accept him again.
In order to disguise MAN's his identity, KIT lied that he was ordered to seize adulterer. HENG tried to look into MAN's record which had already been changed by KONG. It made BROTHER B believed that MAN had been a scapegoat for his big brother and was chivalrous.
ICAC also found out a policeman TAI was involved in the case of HENG. They assigned him to be responsible for wiping out prostitution where the target was BROTHER B's karaoke bar. However, BROTHER B was being notified in advance, so the work of ICAC was in vain. In fact, HENG and TAI were ex-colleagues. On the surface they were against each other but actually they were on the same boat.
KIT was beaten cruelly by HENG as he owed him money. He decided to take revenge. ICAC discovered that the secretary of a police superintendent was very close to TAI. They made relevant arrangement with the police. The secretary got information by tracing the writing and then informed HENG. CHING was working in the karaoke bar, MAN demanded her to leave. TAI 'as usual' swept prostitution. BROTHER B was arrested but he denied the charge of corruption. POK was angry after knowing CHING working as a PR and slapped on her face. FONG asked CHING to stay with her temporarily. BROTHER B and HUNG mentioned that FAI had overheard their conversation and believed she was the undercover. When HUNG tried to kill FAI, MAN arrived and hit her with a wine bottle. FAI was fainted.
MAN drove to the pier and deliberately left a note asking for help. ERIC and LEI gave out a diskette after they were on board where BROTHER B intended to kill them. FAI was being thrown into the sea, MAN revealed his real identity. At the same time, KONG arrived and YING shot at BROTHER B. MAN then saved FAI immediately. KIT was suspended from his duty which he felt hopeless.
MAN and FAI came to a dockyard and SUN was murdered. FAI by mistake hurt MAN. MAN didn't tell the truth which might affect FAI's career. FAI was impressed. ICAC suspected that someone had used SUN's account to conceal the illegal money. In addition, they laundered money by donation to charity organizations.
YING separated with KONG at his birthday. She missed him very much. ICAC team worried about them due to their strange behavior. YING assigned MAN and FAI to protect CHUNG which FAI felt happy.
KEI realized that someone was in the warehouse and tried to put him to death. KIT pushed down some racks and escaped. KIT was threatened to repay his debt. By his clever contrivance, KIT extorted KEI for three million.
MAN was compelled to give out the film as he was afraid that KIT might hurt FAI. KIT brought KEI the film in order to save SHAN. KEI intended to kill them by exploding the taxi they were taking. However, they were being saved.
