Since the death of his wife, Christophe is a control freak. When a supervisor is declared absent for the snow holiday camp right before Christmas, Christophe volunteers, but his son Victor and Marina the biology teacher are not too enthusiastic about it. Christophe feels confident until he is gifted with a mysterious power: he can hear the teenagers' every thoughts.

Three childhood friends - Elise, Sonia and Cecile - leave for a summer in the South of France to help clear Cecile’s holiday house before it is put up for sale. There, they soon become the prime targets of three horny young men, for whom these single forty-year-old women are much more attractive than girls their age.

Murders in... is a collection of French-Belgian police TV movies taking place each time in a different French city and region.
