Jean, a forty-year-old struggling out-of-work actor, has hit rock bottom. Although open to any kind of work, he can't get a break. At the unemployment office, his counsellor has a rather odd proposal: he can get a job helping the police reconstruct crime scenes, by standing in for the dead victim. Jean's obsession for detail impresses the detectives, allowing him to take a leading role in a sensitive investigation in a ski resort, during low season, after a series of murders.
A 40 ans, Jean, comédien, est dans le creux de la vague… Au pôle Emploi Spectacle, sa conseillère lui propose un job un peu particulier : prendre la place du mort pour permettre à la justice de reconstituer les scènes de crime.
