Josefine Preuss in "Stühle im Schnee" ("Chairs in the Snow") (2007) -
IMDB
Klara (Preuss) gets kidnapped by a man who takes her to his basement workshop where he strips her and locks her in a box. She stays there for many days. He only takes her out to rape her, to wash her and... to teach her about carpentry? (What a strange way to find new apprentices!)
The short film drama was originally created for a German film festival. Needless to say, it sparked controversity. Preuss was 20 or 21 when the movie was shot, although she looks younger in it. That impression was boosted by the fact that she was formely best known as the star of a kids TV show and a family sitcom.
