Everyone in the village of Bouzolles knows the Tuche family, who live by the philosophy "Man is not made to work." Despite their lack of money, they strive to be happy... that is, until their hand-to-mouth existence is turned on its head. After winning the lottery, the Tuches get rich beyond their wildest dreams and move to Monaco. And while attempting to fit in in their swanky new homeland, they struggle to stay true to the same principles by which they've always lived.

Les Tuche, a modest french family, change his life after winning a super lottery. Thanks to the money of his parents, the son, Donald (aka "coin-coin) goes to Los Angeles to improve his english. On the L.A. University, he meets Jennifer, daughter of a famous American financier.

After a groundbreaking presidential election, Jeff Tuche becomes the new President of France and moves in the Elysee with his family to govern the country.

After having resigned from his post as President of the Republic, Jeff and his family are happy to be back in their village of Bouzolles. As the end of the year holidays approach, Cathy asks for a unique gift: to reconnect with her sister Maguy, and her husband Jean-Yves, with whom Jeff has been angry for 10 years. The reconciliation could have gone smoothly, except that during a lunch, Jeff and Jean-Yves, will once again find a subject of contention: Christmas. This family feud, which should never have left Bouzolles, will turn into a standoff between Jeff and a giant of Internet distribution.

When Jeff and Cathy’s grandson Jiji is selected for a training camp with Arsenal, it’s a dream opportunity for the whole family to head over to England and meet the royal family.
