In 1960s Quebec, Agathe, an asthmatic child with a vivid inner world, grows up in an isolated suburb, lulled by the haunting sounds of a passing night train that spark her longing for an elusive elsewhere. Her mother Thérèse (the remarkable Larissa Corriveau), a secretary by day and artist by night, creates a tender, offbeat daily life with her flamboyant friend Maurice, a fashion designer. As Agathe grows up, she meets Frank (Lennikim), a young writer whose dreams of a Japanese heroine strike a mysterious chord within her. For her directorial debut, the great Marie Brassard crafts a mystical and mesmerizing, visually exquisite tale, where past and future, dream and reality intertwine. Infused with mythological legends, quantum physics, and magical realism, this coming-of-age journey is also a moving exploration of identity and the mysteries of space and time.
