Franco de Angelo, a vicious gangland criminal, stood in the dock scowling at the jury as he was sentenced. He was pronounced guilty and the judge gave him the maximum sentence. He told Franco that he and the jury thought he was a thoroughly bad lot. Franco vowed to take revenge on every last one of the jurors. He was taken from court, but escaped on his way to jail, together with the police wagon, and disappeared. Two years later the eleven remaining jurors were killed in the space of twenty-four hours. Detectives Bland and Boyd were brought in to track him down, and prevent him from killing again. However Franco had gone back to his secret identity, and the killing had not stopped.
