This crime drama chronicles the doomed exploits of a fugitive convict who believes that he has stolen a cannister filled with heroin. The police are hot on his tail, but not for the reasons he thinks. The authorities know that the crook is really in possession of a leaky container filled with highly radioactive cobalt 60 and they are fearful that he will inadvertently expose the public to deadly radiation. The fleeing felon gets progressively sicker as the chase wears on. He dies and the container is left for others to find.
