Arthur Du Fuss, bitter, alone, and ignored by his neighbours, has two secrets: one dies with him when he commits suicide; the other is the vast wealth he amassed through the creation of a cult board game.
Now his erstwhile neighbours receive a post-mortem invitation to the offices of a charismatic City lawyer to play a final version of the game; the prize - Arthur's fortune. As they dice with the devil, the game first exposes the fragility of their relationships, and then tears them apart, with tragic and horrifying consequences. But Arthur, too, must pay for his revenge. The old man learns that outstanding debts can still be called in, even when you are dead.
