Wealthy Lewis Nelson hires Ray to keep his much younger, gambling-addicted wife Lorna away from the casino he part owns, as she has run up heavy debts. Lorna persuades Arthur to play the roulette wheels on her behalf whilst she is gated and he wins. Whilst collecting bin-bags of used cards from casinos to sell on, Arthur has also picked up a bag of money Lewis intended to steal from the casino to pay Lorna's debts. He decides to return it - in his own fashion.
