Like every year, Mathys accompanies his mother to the local stock car races. With his friend Titouan, he spots a driver who seems familiar, perhaps his father who abandoned him when he was little. Intrigued, Mathys doesn't take his eyes off him and follows him. To get noticed, the young man will take all the risks during a wild race.
Mona lives with her adult son, Joël, who is "slow," as they say. He works in a specialized facility and is passionately in love with his coworker, Océane, who is also disabled. While Mona knows nothing of their relationship, she eventually learns that Océane is pregnant, and the symbiotic bond between mother and son falters.
