After France fell to Germany in 1940, the Vichy regime was set up under Marshal Petain.

Some got away. A few rose to power.
At 5:00 am on June 29, 1944, in Rillieux-la-Pape, France, seven Jews were executed. Many years later, the Nazi sympathizer (Michael Caine) who was responsible for their deaths is living a quiet life in southern France when a new investigation is launched. He finds himself the target of a famous Nazi hunter (Tilda Swinton).
