Flying Squads

LAU CHUEN HUNG, his sister CHUEN FONG and their friend CHEUNG HO NAM are taken hostages by robbers on a mini-bus. Being bold and daring, NAM tries to deal with the robbers and eventually helps the police to arrest the robbers. This wins him praises from the Police Inspector LEE TAT FOK. Encouraged by FOK, HUNG, NAM and their friend CHENG SING attempt to join the police force. In the end, WAM and SING are admitted but not HUNG who gets infuriated and perplexed.

Later, HUNG finds out that the reason for his failure is due to his father's connection with the underworld. Feeling disappointed and angry, he quarrels with his father KUEN. NAM's sister NG dislikes NAM being a police and asks him to quit the job. It just happens that FOK has asked NAM to act as a secret agent to crush a case. So NAM lies to his aster that he has left his job and this delights NG. With the help of his partner, NAM starts working for the underworld but is discovered by HUNG. Having to keep his real identity a secret, misunderstanding arises between NAM and HUNG. This greatly disturbs NAM who is determined to crush the case as soon as possible. Also, from his partner he learns that the life .of a secret agent is in no way an easy one. At the same time, NAM gradually gains the trust of the ringleader.

NG finally gets married and immigrates to Canada. Sadly she says goodbye to all her loved ones in Hong Kong. KUEN thinks that NAM is in financial trouble and so driven to work in the underworld. So he lends money to NAM who is greatly impressed. At the same time, KUEN and HUNG finally reconcile and come to a better understanding of each other. NAM and his partner help the ring-leader in a robbery. When they are celebrating their success, the ring-leader accidentally discovers the real identity of NAM's partner and tries to kill him. NAM attempts to save his partner who finally kills himself so as not to get NAM endangered. His partner's death makes NAM determined to avenge for him.

Upon their success in the robbery, NAM urges the ring-leader to sell the loot to another gang, hoping that through this he can get both gangs arrested. At first, the ring-leader refuses to follow NAM's suggestion. After much work done by NAM, the ring-leader finally gives his consent. NAM informs FOK of the meeting place of the two gangs. Eventually, both gangs are all arrested. FOK appreciates much NAM's courage and efficiency. He recommends him to join the flying squad. Encouraged by NAM, SING also applies and both of them get admitted. NG suddenly re turns from Canada because her marriage breaks. KUEN offers her much consolation and advice. One day, NG faints after taking the wrong medicine. KUEN sends her to the hospital thinking that she attempts suicide. In the meantime, NAM gets so involved in his work that he cannot get the time to visit NG and misunderstanding arises between KUEN and NAM.

In the flying squad, NAM and SING get acquainted with another group headed by COOL. The two groups do not get along well with one another. COOL often makes fun of NAM who tolerates his ridicule with patience. SONG, an enemy of KUEN, returns from Holland to avenge on KUEN for his former betrayal of him and his brother, victimizing them to become prisoners for years. SONG blackmails KUEN who promises to pay him in order to make up for his own fault. However, SONG kills KUEN after getting the money. KUEN's followers want to take revenge for KUEN and chase after SONG. Having got hold of the cremated remains of KUEN's body, SONG forces HUNG to negotiate with him. Being ridiculed by SONG, HUNG loses his senses and kills SONG.

In order to avoid trouble, HUNG takes refuge on Lantau Island. A former follower of KUEN, CHUNG, now takes over KUEN's place. The gap between NAM and COOL widens. Enmity even breeds when the two of them strive to become leader in the flying squad. Later, NAM is attracted by a beautiful police inspector LEE KIKI whom COOL claims to be his girlfriend. COOL even stops NAM from courting her. On the contrary, this makes NAM even more determined to win her heart. On learning that NAM starts dating with KI, COOL gets infuriated and this deepens their hatred for each other.
