When two acrobats are fired for fighting with punks in the audience, they go live with an aunt who's being pressured to sell her house. The developer's nasty son, Lee Fu, decides to muscle the sale and soon he's at war with the acrobats.

Ah Chi (Ka-Yan Leung) is obsessed with the martial arts and, more often than not, his kung-fu clowning gets him into trouble. Ending up facing Hsia (Eddie Ko) of the notorious Jade Brotherhood is inevitable. As a result, Hsia forces Chi's martial arts master to expel him. Masterless and working for a fish vendor, Chi meets a crafty kid (Yat Lung Wong), whose uncle Chow Tung (Chin Yuet Sang) is a master of the Insane Mantis style. The Jade Brotherhood aims for control of the small town but Chi is training with a new Master and will not accept bullies in the neighbourhood.
