When Ho Nam and his friends are beaten by Hung Hing's "Ugly Kwan" (Francis Ng) and his men following a misunderstanding, they decide to join the society, following Bee.

Ten years later, in 1995, Ho Nam and his buddies have established themselves as Bee's enforcers, performing their first successful hit on Kwan's associate "Ba Bai" (Joe Chen).

One day, Bee is tasked with an assignment by Hung Hing chairman Chiang Tin Sung (Simon Yam) to head to Macau and perform another hit.

Friendships begin to tear apart when Chicken's girlfriend and Ho Nam are kidnapped and drugged by Kwan's men into sex, videotaping their actions as proof of violating secret society rules.

At a Hung Hing summit, Kwan accuses Bee of failing the hit and Ho Nam for breaking the society "code" of sleeping with his best friend's woman, with the videotape as evidence.
