Julián Lemar, a best-selling suspense writer, goes on vacation with his family to a cabin in the woods. During a strong storm, the power goes out and a woman shows up desperately asking for help: her husband killed her son and now he wants to kill her. From that moment on, danger and deception are a constant threat and for Julián a hellish night begins until he discovers the truth.

A veil of sadness lies over the oppressively hot summer days. Cleo dives into daydreams with her cousins, the girls share secret signs and rituals. Flowing gently, in impressionistic images, the empty space that the death of Cleo’s sister has left in the family is poetically encircled.
