Burglar John "Duke" Anderson (Sean Connery) is released after ten years in prison. He renews his relationship with his old girlfriend, Ingrid (Dyan Cannon). She lives in a high-class apartment block (Convent of the Sacred Heart (New York City)) in New York City and Anderson, almost instantly, decides to burgle the entire building in a single sweep – filling a furniture van with the proceeds. He gains financing from a nostalgic Mafia boss and gathers his four-man crew. Also included is an old ex-con drunk, "Pop" (Stan Gottlieb), whom Anderson met in jail, and who is to play concierge while the real one is bound and gagged in the cellar.
