In this lightweight comedy, David McCallum stars as Stanley Thrumm, a retiring British tour guide who strikes it rich one night in a casino on the Riviera. He's not sure that he wants to take the cash back to England, because he'll have to pay taxes on it, so he decides to put it in a Swiss bank account. But Carla Moretti (Sylva Koscina), an apparently helpful woman whom he has met, has designs on the loot, and she enlists her ex-husband in an effort to get it. Thrumm takes his winnings on a roundabout trek to Switzerland while Carla and her husband pursue, and the result is a long car chase with many comic diversions and a lot of Alpine scenery.
