The corpse of a woman, horribly mutilated. The crime scene shocks our investigators. It is clearly the work of a psychopath... Who seems to be Hamel, a young man suffering from psychic disorders, nightmarish visions... which are those of the crime scene! Hamel, who confides in his psychiatrist, is very quickly arrested following a second similar murder. Too easy ? In any case, this is the opinion of Marijo, who embarks on another track, which could well affect her much more than she thinks. At the same time, she is worried about Darius, like Ben and Duchess. Darius seems to have completely lost his mind. And they are not wrong: to save his sister, he will commit the irreparable... and will risk paying a high price...
