An architect's house lost in the woods. One morning, Isabelle and Richard Deloye are sequestered in their home by a hooded and armed intruder. What does he want? Steal, rape, kill? Or anything else that the couple doesn't yet know...

20 years earlier, Richard's student was Mohamed. Frustrated at having to work in the factory while he dreams of becoming a writer, he regains hope thanks to Isabelle who wants to help him. But a resounding intrusion changes their meeting.
