Charles Salt (Sammy Davis Jr.) and Christopher Pepper (Peter Lawford) are owners of a nightclub that is about to go under. The two seek help from Pepper's wealthy twin brother, Lord Sydney Pepper, who promptly denies them a loan. Undaunted, Pepper returns once more and finds his brother murdered. He chooses to view the untimely death as an opportunity, posing as his sibling to keep the club afloat -- except his brother was a diamond smuggler, and his accomplices are still after him. Wikipedia
