Kleinhoff Hotel (1977)

Pascale, married to an architect, misses her flight to London and is forced to stay in Berlin, at the Kleinhoff Hotel where she stayed as a student. Karl, a would-be revolutionary, lives in the adjoining room and Pascale spies on him and his ex-girlfriend through a hole, then follows him to a questionable place where she is arrested by the police during a revolutionists' raid. When she returns to the Kleinhoff Hotel, Pascale finds Karl crying, enters his room to console him and they have a love affair. While she sleeps, he kills himself; upon awakening, she coldly dresses and leaves the hotel.
