A black comedy in the snow: a bear causes the death of two drug dealers. The loot ends up in the hands of Cathy and Michel, a naive couple full of good intentions. Will they escape the suspicions of the local inspector, who is more preoccupied with Christmas preparations than the investigation? The Jurassic setting created by comedian and director Franck Dubosc - who also stars in the film - is reminiscent of the Coen brothers' Minnesota in “Fargo”: snow-covered landscapes, a criminal case on the border between two states and characters whose stupidity is hard to beat. The chain of events is as absurd as the presence of a bear in the Jura.
