Michel and Cathy live a quiet life in the mountains, trapped in the routine of a marriage with no surprises in sight. Everything changes in an instant: a bear causes an accident that leads them to accidentally kill two drug traffickers – and to discover a suitcase containing more than two million euros in the trunk of the vehicle.

The temptation is immediate. They decide to cover up the incident and keep the money. What follows is a storm of consequences: radical shifts in their relationship, darkly comic criminal entanglements, and the growing attention of a local police force that starts asking uncomfortable questions.

At 113 minutes of pure adrenaline, Mystery on the Mountains is a film that never lets you breathe. Every twist raises more questions than answers, and between nerves, awkward silences, and unexpected laughs, the suspense becomes irresistible. Critics have compared it to Fargo, but with the warmth and irony of the very best contemporary European cinema: witty, sharp, and far beyond what you’d expect.
