In this entertaining Hong Kong comedy-action-drama, five creatively-named criminals (Teapot, Vaseline, Exhaust Pipe, Curly Jerk, and Ranks) get out of prison and decide to "go straight" by starting a cleaning business. One of their customers is the underworld counterfeiter "Boss Chau," also released from prison but still committed to his chosen vocation. An ace detective (Jackie Chan) is about to grab Chau's counterfeiting plates when the cleaning crew accidentally make off with the plates while doing Chau's house. Their troubles only increase when they learn that the younger sister of one of them (and love interest of three) has been kidnapped by the rival gang leader "Boss Man" and is being held in exchange for the printing plates.
