After getting into a teen brawl to protect his friend, Zach (Ian Fang), one night while watching a Getai performance, Jianhao (Edwin Goh) gets sent to a Boys' Home for six months.

His mother, Huifang (Chiang Tsu-ping), arranges for him to help out in her stall at Bugis Street.

However, due to his loyalty to his "brother" Zach, he follows him to join a triad gang, Yi Ren Tang, led by Zhihua (Li Nanxing) to get protection against a rival gang, Gang 660, which was run by their enemy, Alex's (Xavier Ong) father, Guodong (Liu Kai Chi).

Huifang seeks Zhihua's help, revealing that Jianhao is actually his biological son which she refused to abort 17 years ago.

The police arrive in time just before Guodong is about to hit Zach with a metal pipe.
