Bob O'Neill (Bob Steele) is on the hunt for his father's killer. Because his father was killed using poison gas, O'Neill's prime suspect is a deformed, mysterious scientist named Otto Zenz (Bill Quinn). When Zenz skips town, O'Neill follows. Before he catches up with his target, O'Neill finds himself on the other side of the law after being accused of holding up a mail truck. But he won't give up, so he finds a way to continue his pursuit -- as a man on the run himself.
