Welcome to the No Sleep Club where you are never alone in fighting insomnia. The three members of the Club, including the hot-headed and now unemployed chef who often goes on profanity-laced tirades, Tina, a runaway forbidden by her parents to pursue dancing, and William, the poet who feels underappreciated. They share a common objective: to be cured of insomnia and leave the Club. Chi, the latest chairman of the Club, is in charge after losing both his girlfriend and his sleep, bringing a breath of fresh air and a new goal to the Club.

Sum, son of a policeman, is bullied at school and finds no comfort or care at home. As the demonstrations and violence in Hong Kong escalate, he suffers more violent and humiliating bullying. Wing, Sum's father, also faces enormous pressure under investigation of police brutality. The rift between father and son widens as the latter is increasingly abused and isolated at school. Things get out of control when the angry Sum unexpectedly finds a gun amidst the upheaval.
