German director Alfred Vohrer often based his films on popular novels written by the likes of Edgar Wallace and Johannes Mario Simmel. British novelist James Hadley Chase's book Pay or Die was adapted to the screen for this Vohrer action feature. After denying a crime syndicate 100,000 pounds on demand, a British millionaire is soon dead. His nephew Don (Gotz George), heir to the fortune, is determined to get his vengeance and begins his own search for the guilty parties. It would seem Don has fortune on his side as the gang boss (Richard Muench) is having problems not only among his men, but also with his woman (Hildegarde Knef).
