The Trial(1968)

Bistra and Evgeny, first year university students, are in love and inseparable, but slowly with time Bistra becomes infatuated with Evgeny's dad, as she sees him as the embodiment of what her dream lover would be. Shocked and distressed at this revelation, Evgeny hits a pedestrian with his car. Bistra's the only one who can help him in court if she's willing to admit what they talked about before the crash.
