Several notables from the Chamonix region are found murdered in their homes. To move forward with investigation, police captain Thomas Delhaye decides to release Juliette Hémon from prison, imprisoned for a strangely similar case.
The 19 years old Thomas wakes up in a hospital after three years in a coma. He doesn't remember anything. The psychologist Anna tells him that his family has been murdered and that he is the only survivor of the massacre while his sister Laura is still missing.
