Five strangers in prison became good brothers - the Five Lucky Stars. Teapot (played by Sammo Hung), Death Throat (played by Ng Man-tat), Curly (played by Sham Kin-fung), Vaseline (played by Chin Cheung-lam) and Lucky (played by Fung Sui-fan) were all taken advantage of for petty theft or minor roles. They were determined to start a new life after being released from prison and make money honestly. The five were released from prison on the same day. After being released from prison, they jointly established a cleaning company, specializing in cleaning companies or homes. One day, the gang was caught by a local policeman while trading and selling fake electronic plates. In a panic, they hid the electronic plates in the cleaning box of the Five Lucky Stars' cleaning car. The Five Lucky Stars, who were unaware of the situation, were involved in the right and wrong of the underworld again: on the one hand, the police suspected that they were gang accomplices and were wanted everywhere; on the other hand, the gang was also chasing them, wanting to kill them and get the electronic plates back. How did the Five Lucky Stars use their ingenious strategies to escape from the dilemma?
