The Collaborator(1970)

During the years of the German Occupation, Dimitris Korres, commander of a police station, is considered a collaborator of the occupiers but everyone, even his daughter Maria, is wrong as he, code-named "OP 34", is one of the leading members of the Resistance. From his post he helps Greek patriots and saves the lives of prisoners, such as Lieutenant Avgeris, whose plane was shot down in Greek airspace. Avgeris is in love with Maria, who tries to help him flee to the Middle East, but they are captured by the Germans. Avgeris, in order not to be harmed, agrees to cooperate with them.
