In London, George Thomason, his seductive American girlfriend Wanda Gershwitz, and their associate Ken Pile are planning their latest crime, a diamond heist that should net them £13 million. They plan on leaving the country with the goods after the heist. On Wanda’s recommendation, they enlist the help of her brother, Otto, a weapons expert, for this heist. In reality, Otto is not Wanda’s brother, but her latest lover, a dimwit who gets off on his own body odor, who believes he’s an intellectual because he reads Nietzsche, and who does not tolerate being called stupid by anyone.
