Chester Schofield, a young American, wins half of Sir Cuthbert Ware-Armitage’s father’s factory in a poker game. Not content with his winnings, he proposes a double or nothing game to his opponent, which will be played on the tarmac. The two men entered the Monte Carlo Rally. In this 2000 km long competition, they will have to deal with tough crews such as two Germans (who are in fact carrying a hoard of money), or the two Italian policemen or the team of French feminists who are not afraid of the cold. To win – and get his father’s factory back – Cuthbert does everything within his power.
