Lyne and her watchmaker companion Vincent make the Univers workshops prosper. The young Quebecer thought she was done with her visions when new flashes appeared to her, leading to the discovery of a corpse in the Creux-du-Van. While Vincent compromises himself in a partnership with a Russian businessman whose methods are not very transparent, new bodies are discovered in the woods. The victims were all killed and buried by the same murderer. These successive exhumations awaken painful memories among the inhabitants of the region. The investigation progresses thanks to Lyne's visions and helps explain mysterious disappearances that have occurred in recent years.
