Daniel seems to have it all: professional success, financial prosperity, and a fulfilling family life. But when he is convicted of financial fraud, the world he has so carefully built for himself suddenly comes crashing down. Instead of his luxurious apartment in Neuilly, he now finds himself in a nine-square-meter prison cell in Poissy. From one day to the next, he must navigate an environment whose rules are completely foreign to him.

But Daniel possesses qualities that no one can take away from him: quick wit, humor, and the ability to connect with others even in difficult situations. And so, what begins as an unwanted new beginning turns into a moving and surprising story about resilience, humanity, and what happens when people from very different backgrounds and faiths come together.

Inspired by a true story, the film tells a heartwarming and comedic tale of the power of mutual support, even where you least expect it.
