It's 1978, in Châlons-sur-Marne, in Champagne, France. Christine, age 16, has dreamed of John Travolta ever since seeing him in the film, Saturday Night fever. Nicolas, age 17, is a very private, weird young man, "flipped out" by the writings of Rimbaud and Nietzsche. To please one of his friends, Nicolas makes a bet : "To pick up a girl, all you have to do is want her". When he meets Christine for the first time on a bus, Nicolas tries to pick her up. For him, she's just part of a game. But for her, it's love. Her first.
