The glamorous  advertising executive Mary is sent from USA to take over the Hong Kong branch of the company.  As Mary arrives in Hong Kong, she witnesses the funeral of Kung Fu superstar Bruce Lee and sees the potential profit that could be made.

One day whilst out travelling around, a Taxi driver and kung fu expert Lee Tien-Yee catches the attention of Mary due to his resemblance to Bruce Lee. She sends out her assistant to track down Tien-Yee and then persuades him to sign a contract with her company. Mary has big plans for Lee and hires a host of staff to build up his profile.

To improve his kung fu skills, she hires a master to teach him. Lee Tien-Yee doesn’t think too much of his new teacher, and he especially doesn’t like the criticisms of his technique. But after awhile, he soon grows to like him.

The growing popularity of Tien-Yee soon causes a strain with his long-term girlfriend Hsiao-Chun and the two split up. Seeing the opportunity, Mary arranges for a famous french film actress to begin dating Lee instead.

As Tien-Yee embarks on a overseas tour, he finds himself fighting off many challengers hired by Mr. George from a rival advertising company. George forces him to engage in a contest against a fighter he has hired especially from America by kidnapping Hsiao-Chun.
