Maurice, a professional gambler, is barred from a casino after a large win. Later, he is beaten up and the winnings are stolen. When he hears of a big poker game, he has to sell his car to Arthur to raise the stake money, and gets Terry to guard him.

Terry guards a group of people that Maurice the gambler has put together to win at roulette. When the casino starts to protest, he hides them out at his flat, but this upsets his girlfriend Penny, who has taken the week off to be with him.
