After graduating from high school, Yanis and his friends Barnabé, Thomas and Max left Plougastel and moved to Paris... as roomates! Roommates = total freedom. Paris = a centripetal force where evrything seems possible: studies, professional opportunities, parties, encounters. For Yanis, our main character, the stress is mixed with excitement. His parents have made it clear that they'll take him back at the first slip-up... But it's not easy living together without a few stumbles, even less so at a time when everyone's trying to find their place. Conflicts, love affairs, student insecurity, loneliness when everyone's out but you, social pressure, jealousy and power struggles... All this will turn their little microcosm of friendship upside down. With adolescence that drags, they tell themselves that anything is possible, a swipe, a click, a like, and off it goes. But in the end, they end up asking themselves: at what age can you stil say you've got your whole life ahead of you?
