The film cuts between two seemingly unrelated stories. One, set in present-day Montreal, focuses on Antoine, a successful club DJ torn between his new girlfriend Rose and his still-complicated relationship with his childhood friend and ex-wife Carole; the other, set in 1960s Paris, features Jacqueline, the fiercely protective single mother of Laurent, a child with Down syndrome who has a crush on Véronique, a friend and companion who also has Down syndrome.
