"Marie Baie des Anges" is the tale of one summer in the life of two tempestuous adolescents on the shimmering, sun-drenched Riviera.

Marie (Vahina Giocante) is 15 and the Lolita of the beaches. You only live once, and she's resolved to make this the summer that she does it all. Strutting through the streets of the bay she turns the heads of the local boys, but sets her sights on a group of American sailors. They take her in, feeding and entertaining her, and these conquests fulfill her dreams of nightclubs, champagne and older men.

Orso (Frederic Malgras) is a 17-year-old delinquent, capable of anything. He roams the forests and beaches of the Baie des Anges, the bay of angels, with gangs of other lost boys, lawless and wild in a violent world. But Orso stands out from the groups of other kids with his fierce and menacing air.

After a hesitant first meeting, Orso and Marie realize they are drawn to each other. They run away together to a hidden, idyllic island, but their refuge in this secluded paradise can't last. Orso's thirst for danger nags at him, and they return to his rough and tumble life, where they are engulfed by a giddy spiral of crime that has only one way out.
