Parole De Flic (1985)

Synopsis
The sentiments of producer, co-writer, and star Alain Delon provide the particular slant in this routine thriller about vigilante justice over other vigilantes. The angry hero (Delon) leaves France in a fury because of a technicality in the justice system that failed to convict the murderers of his wife. After lazing away his days in a Congolese village, sleeping with whatever woman he chooses or playing cards, he finds out that vigilantes have murdered his daughter because they are intent on ridding France of undesirables -- which include delinquents (a category mistakenly attributed to her) and North Africans, as well as drug dealers. Now really out of control, revenge propels the bereaved father to return home and murder the vigilantes one by one, maiming them first to watch them suffer. Justice, of course, is too blind to catch up with him. ~ Eleanor Mannikka, All Movie Guide
