It's 1972 and reporter Franck Jourdan is getting obsessed in an investigation to bring Paul Touvier to trial for crimes against humanity. During his quest, Jourdan discovers how Touvier remained hidden from the authorities all those years.

In 1972, France under President Pompidou has just one wish: to be done with reminders of wartime collaboration and be a unified nation at last. However, the ghosts of World War Two return when Klaus Barbie, the Butcher of Lyon, is found in Argentina. Franck Jourdan, a special correspondent with a French political magazine, dives into this investigation with passion, determined to see Paul Touvier condemned for crimes against humanity. The clever cat and mouse game that Touvier has been cleverly playing since the end of the war will lead Jourdan to where Touvier committed his crimes, and show him how he managed to escape justice for so long.—Happy_Evil_Dude
