Caine is a small-time crook who, along with British patriot Coward, carries out a planned robbery of a gold shipment. Their scheme involves causing a major traffic jam in the middle of Turin, Italy, which allows them to steal gold ingots from an armored car. The gold is then stashed in a bus, and the predictable chase ensues. A fleet of cars winds through the Swiss Alps, with the crooks' bus nearly going over the edge. Caine and Coward teeter on the brink of disaster for a few moments before they all make it to safety. Hill plays an insane computer wiz who joins up with Caine and Coward.
