Cheng Kuo-Tung (Ho Chung-Dao) has a great amount of respect for Bruce Lee and strives to be just like him in martial arts. When the news hits the papers that Bruce Lee has suddenly died, he finds it impossible to believe and decides to go out and drown his sorrows. Whilst sleeping off the alcohol, Kuo-Tung is visited that night by the ghost of Bruce Lee in a dream.

With the dream still on his mind, Kuo-Tung goes to a temple to see the monk Wo Ming to seek his advice. To prove that he has the skills to be able to fully investigate the death of Bruce Lee, the monk arranges a test against a group of his students, followed by a deep mediation. During the mediation session, he once again has a vision of Bruce Lee but this time, it is revealed that Bruce was badly wounded during a fight and that is why he later died.

Determined to find out the truth behind Bruce Lee’s death, Kuo-Tung starts his investigation by talking to some of Bruce’s friends. He is offered a bribe by gangsters to leave and forget about looking any further into the matter. When he refuses, they hold his brother Pao to try and make him change his mind.

Saving his brother from the gangs clutches, Kuo-Tung uses his likeness to Bruce Lee to scare those responsible into thinking that they are seeing a ghost seeking revenge and find out what really happened the night Bruce died.
