This film is the debut work of Bruce Lee's son Brandon Lee after he returned to Hong Kong. Unfortunately, the script was clichéd and his acting skills were a bit immature, so he did not become a hit. A few years later, he turned to Hollywood to make movies, but he died unexpectedly when he was about to become famous, which is a pity. Directed by Yu Yantai, this film describes the simple-minded Brandon who thought he was helping his friend Guo Bao (played by Michael Wong) and accidentally killed a policeman and was imprisoned for six years. In fact, this was a trap deliberately set by Guo Bao to harm Brandon, and he took the opportunity to rape his girlfriend. After learning the truth, Brandon wanted to escape from prison for revenge, but failed. Six years later, Guo Bao took over his father's underworld business and did even more evil. The mature Brandon decided to bravely go into the tiger's den to seek justice.
