Fatum: Room 216


Fatum: Room 216 - Documentaries about serial killers

The room 216 of a police station in Ontario, Canada, will be the site of the events of a very particular interrogation. The protagonists are detective Jim Smith and a military colonel suspected in the murder case of Jessica Lloyd, a woman who has been missing for several days.

The documentary is a synthesis of a claustrophobic 10-hour long interrogation in which Detective Smith uses the stereotype of the good policeman to, little by little, dig into the soul of the suspect, who gradually yields to the truth and finally describes with visceral detail how the woman was abused, killed, and disappeared.

The documentary ends with a devastating act of sincerity by the suspect when asked by Smith. A documentary as rare as it is unsettling.
