The murder of a beautiful chambermaid becomes personal when prosecutor Elisabeth Brochène discovers that the victim seemed to be interested in the police lieutenant Marie Balaguère. During the investigation, Marie Balaguère finds out that one of the client of the hotel where the victim worked appears to be her biological father from whom she never heard before. She quickly discovers that he's a con artist. Despite not knowing him she doesn't see a suspect in him. The fact that the prosecutor ads him on the suspect list is putting the friendship between the two women in jeopardy.
