In September 2021, France will celebrate the 40th anniversary of the abolition of the death penalty. A decision so strong that it will symbolize, in itself, the first seven years of François Mitterrand. For Robert Badinter, it was the fight of a lifetime, rooted in a personal history marked by the rejection of injustice, which began after the arrest of his father by the Gestapo in 1943. A story told through archives and by his family and closest friends.
