'Nazi Hunters' episode on the Catholic Church protecting French Catholic Nazi Paul Touvier (2010)

Nazi Hunters: Nazi Hunters: Paul Touvier https://www.natgeotv.com/ca/nazi-hunters/about
One of France's worst wartime villains, Paul Touvier is an overtly anti-Semitic traitor who terrorizes his own countrymen. As a leader of a pro-Nazi paramilitary police force, he relishes his job of hunting down 'enemies of the state' and, murdering Jews and resistance fighters alike, earns himself the nickname the 'Hangman of Lyon'.

A devout Catholic, Touvier escapes retribution after the war by turning to the church for help. By 1988, France's most notorious war criminal is still at large, and a high-ranking French investigator, Jean-Louis Recordon, is given the job of hunting him down. After 40 years, it is a nearly impossible mission.

Recordon starts with his last known address — the archdiocese in Lyon. As the investigation unfolds Recordon discovers that a shadowy right wing movement within the Catholic church is hiding the Nazi collaborator. The manhunt takes detectives to secretive religious orders all over France. It also reveals that the deep divisions caused by the war live on.
