Excursion (1966)

1941 and the war culminates. The wife of a lieutenant and a sergeant fall madly in love. Times and circumstances -military service, marriage, friendship between the two men- forbid this love, but do not negate it. When the lieutenant is injured and taken to hospital, the two lovers, against all odds, dare the only possible way out: he defects, she leaves her husband, and they begin a journey without return towards the border.
