A jewel thief's nephew is sent along on a heist to ensure a longtime partner in crime stays honest about the division of the loot.

Master thief Joe (Hackman) decides to call it quits after a profitable jewel store robbery in which his unmasked face is caught on camera. Trouble is, he's already committed to another, bigger job--stealing a gold shipment from a Swiss freight plane--for his fence & paymaster Mickey (Devito).
