The police catch Zorro, a small-time crook who is to testify as a key witness in a trial against organized crime. When an assassination attempt is made on him in prison, Zorro is to be given a new identity and the prosecutor decides to let him go into hiding until the trial begins. The experienced and cunning inspector Fütterer is to protect him. The policeman and the crook are now completely on their own and become targets of the criminal organization that starts hunting them. In the process, they become something like friends. When they find out that the public prosecutor is also only using them as bait, they narrowly escape the trap set for them and flee to the Caribbean.
