When a woman's (Tilda Swinton) eldest son's lover washes up on the beachfront in front of their house, she does the only thing an unflinchingly devoted mother could: she hides the body to protect her son. Now unexpectedly, in the aftermath of this desperate act, emerges Alek Spera (Goran Visnjic), who knows about the death and the secret life of her son. But what begins as a riveting cat-and-mouse game soon turns into a haunting love story with self-sacrifice at its center.
