Francesco, nicknamed 'Toscano', is a very good pool player but he never wins when he plays for money.

The two fall in love, but in the meantime Francesco loses a big amount of money playing versus 'Scuro', the long-time Italian champion. His only chance to pay the debt is to win the Italian Championships.
