Lyne, a young woman from Quebec, has just inherited the Univers watchmaking workshop in Le Locle. As soon as she arrives in the Neuchâtel locality to settle this inheritance, she has a strange vision and, a few hours later, a man is murdered. The police asked him not to leave the area. The nightmares and murders continue. Lyne meets Vincent, a talented young watchmaker, who passes on his passion for complicated watches. Together, they will save the Universe workshop and go back to the source of the secret.

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.
