Trailer: Locked Up

In a German town, teacher Irene leads an inconspicuous, boring, lonely life. One day, a man rings at her door and slips in. It's an armed convict from the prison next door, escaped with a leg wound. He now makes her a prisoner in her own home. Almost without a word, as if she secretly enjoys the excitement or just mesmerized, she obeys Vassily, every single command, even sexual services, submissively or after a symbolic struggle. Somehow that seems to change, but can force initiate love?
