Channel 5 is preparing a documentary about France's mass rape trial and its victim, 72-year-old Gisèle Pelicot.

Public prosecutor Laure Chabaud told the packed courthouse in Avignon, southern France, on Monday that the sentence would be “long” but “not enough considering the serious nature of these acts.”

Prosecutor Laure Chabaud asked the panel of judges for the maximum possible penalty for aggravated rape — 20 years — against the victim’s now ex-husband. Dominique Pelicot, who turns 72 this week, stared down at the floor, one hand on the handle of his cane, as the prosecutor spoke.

The daughter of Gisèle Pelicot, Caroline Darian, is the narrator of a gripping documentary that chronicles the trial of the mass rape case involving her parents and sheds light on the use of drugs to commit sexual abuse.
