Five childhood friends have long dreamed of sharing a house together. And when the chance comes along, Julia, Vadim, Nestor and Timothée jump at it, especially when Samuel (Pierre Niney - Yves Saint Laurent) offers to pay half the rent. But shortly after they move in, Samuel finds himself penniless and doesn't tell anyone. Instead, he decides to raise the rent money by selling weed. However, Samuel doesn't turn out to be the dealer he'd hoped, and when everything goes to pot, he has no other choice than to turn to the only family he has left: his friends. Five is an authentic and hilarious film about friendship - that family you get to choose with its codes, its customs, and its own language.
