Some say youth is wasted on the young, but they obviously don’t know the teenagers from Genèse. Guillaume, Charlotte and Felix are all shaken up by their first loves in the turmoil of their youth. At a time when others are conforming, they stand their ground and assert their right to love and be free. They remain true to themselves, but not without problems. Philippe Lesage sketches how heartrendingly beautiful love can be, using a patient camera, gripping soundtrack and very charismatic protagonists.
Guillaume is at a boarding school, where he is a leader in the class. He gradually develops feelings for his best friend, an ice hockey player. Guillaume’s sister Charlotte exchanges her respectable puppy love for the wrong type. The third, separate storyline is for Félix, a young teenager who experiences his first pure love at summer camp. This helps explain the film's puzzling title: it’s the start of everything.
