Leo is a young man in his early twenties. Originally from the provinces, he arrives in Paris to find work and settle down. He hasn't seen his father in over ten years. His father left the family home, leaving his mother to raise him alone. Leo was able to trace his father via the Internet. He was living alone in Paris. Leo informed his father of his arrival and asked him to take him in while he found an apartment and a job. When Leo arrived at his father's house, he discovered how precarious his life was. He has taken up residence in a small two-room apartment in a working-class district of Paris, and has been unemployed for a long time. As Leo reconnects with his father, he unwittingly discovers his father's hidden life.

Since their early childhood, Sébastien, Céline and Stéphane were very close brothers and sisters until Céline met Luigi, the father of her son Marco. A relationship that Sébastien and Stéphane did not approve of. This harmful relationship created a distance between the 2 brothers and the sister. Since Stéphane was released from prison, Sébastien, who is less resentful than his brother, will try by all means to reconnect Céline and Stéphane. But, after a tragic event in their sister's life, they have no choice but to help her without knowing what awaits them. The two brothers will venture into totally crazy galleys, with disconcerting clumsiness, each more hilarious than the last.
