Book smart Célène falls for bad boy Tristan at her new Biarritz high school, unaware she's part of a cruel bet he's made with social media queen Vanessa.

Célène, at 17, is idealistic. She believes in absolute love, and is more interested in reading than in social networks. She is getting ready for living apart from her fiancé, Pierre, for a while, leaving Paris for Biarritz. Very quickly, she has to face the evil elite of her new school, ruled over by the former big-screen star and Instagram queen Vanessa and the celebrity surfer Tristan, who's both dangerous and seductive. Célène falls in love with him, but is a long way from suspecting that she is at the centre of a cruel bet between Tristan and Vanessa. Just how far will they go?
