Greene plays an up and coming boxer with a powerful right hand and a heart of gold. He works night shifts in a bar and has a girlfriend whose father played by Ernest Borgnine disapproves of the relationship thinking Greene is a no good for nothing loser. To prove himself Greene catches the attention of a local boxing promoter played by Giuliano Gemma who decides to make a champion out of his newfound protégé.

In 1978, $20 million was stolen from a Detroit bank. One of the robbers was caught, one was found dead, and the third disappeared. The money was never found. Seven years later, the robber who was caught was released from jail. He immediately went to Miami, only to be found dead the next day. Now FBI agents Doug Bennet and Steve Forest have been called in to investigate the case while posing as Miami police officers. Somewhere in Miami the third robber is hiding with his $20 million, and he has a seven-year head start on the authorities.
