The Tuccis, a boorish family leading a modest life in a small Italian village, win € 100 million at the lottery. After failing to keep it a secret, they end up constantly harassed by neighbors and acquaintances, forcing them to leave for Milan to start anew... and openly flaunt their newfound wealth. Soon they'll realize they haven't got the faintest idea how today's upper class actually behaves.

The Tuccis figure out how to get their fortune back and, to avoid paying taxes, resolve to turn the village into a tax haven thanks to a 19th-century legal loophole.
