A House Without Boundaries(1972)
In this Spanish film, Daniel (Tony Isbert) is a member of The Organization. It is never quite clear whether The Organization is part of the government, a secret society, or something else. Whatever it is, it is powerful, and does not take disobedience lightly. He is sent on an assignment to Bilbao to determine what has become of a lad his age, a former member. He takes over the boy's room in an odd rooming house. When he is given the photo of the boy's girlfriend (Geraldine Chaplin), he is so taken with it that he puts off his quest. The Organization requires him to continue, however, so he tracks her down to a remote fishing village. The two fall in love and attempt to escape.
