The story tells about three ordinary people who have never met before. In a critical situation, they join forces to resolve the crisis, and thus get involved in a series of mysterious cases and are hunted by the police and gangs. Julian Cheung plays a novelist oppressed by life, Bosco Wong plays a stuntman who is strong on the outside but weak on the inside, and Chrissie Chau plays a tour guide with a dual identity, responsible for "protecting" the two male protagonists. Moses Chan plays a retired bar owner with a complicated background, and there are many fighting scenes in the play; and Vincent Wong plays a kind-hearted thief.
