Alain, of North African origin, lives with the memory of his sister, kidnapped before his eyes by a neo-Nazi group when they were children. Added to this is the murder of his best friend by the head of security of "La Ligue patriotique", a powerful far-right party. Alain then decides, both out of personal vengeance and political conviction, to assassinate Hugues Henry Lègle, the leader of this movement.
