Ema (Mariana Di Girolamo) and Gaston (Gael Garcia Bernal) are a couple reeling from a crisis. They've just returned their adopted 12-year-old son Polo to child services, after the troubled boy set fire to their home and injured Ema's sister. Their agonising decision spins the marriage into chaos, but the guilt-ridden Ema refuses to let go, and sets out on a strange, secretive, and fearless quest to reunite her family and find Polo at any cost.
