He hates himself, is riddled with envy for others, but is ultimately too weak to think of a way out of his massive debts. Then one day he is approached by a strange man who offers him what seems the solution of a lifetime – to take a short journey on a ship called Espoir, during which time he will be given the chance to win more cash than he can dream of in a card game like no other.
