Henry (Michael Caine) is an alcoholic cat burglar finishing up a drying-out stint at a sanatorium. He's approached by an Italian belle, Fé (Giovanna Ralli), who has a proposition: She and her husband, Richard (Eric Portman), are planning to rob the millionaire Salinas (David Buck) when he's at a concert, and they need a thief to do it. After the heist, Henry, Fé and Richard retreat to the couple's Spanish villa, where hidden truths and scandalous secrets slowly come out.
