Watch WARF (1970) Official Trailer

During World War II, several young people capture a German soldier on the roof of the building they defend and in which they most probably live. One of them ends up staying in the same room with the man for a longer time, keeping an eye on him at gunpoint. The relationship that develops between them, in spite of the language barrier, is suddenly halted by another gun(shot), one that comes from outside the room.
