Carnival in a small town: Margaux, Louisa and Théo are getting ready for a night out. They put on their costumes, drink too much. Each one of them apprehends this evening in a different way. Margaux hopes to meet the boy who will give her her first real kiss. Louisa expects nothing, except a drop of entertainment to pull her out of her boredom. Théo, little brother and friend, wants to get drunk, to waltz, to let go.
