The Cold Room (1984)

Seventeen-year-old Carla arrives in East Berlin to spend the summer with her estrange historian father, Hugh. She stays in an old hotel that used to be a butcher shop. She soon gets the feeling that something is wrong with her room and that it used to be bigger somehow. There she discovers an old wardrobe with a mirror in it. When she sees an image of a young girl in the mirror instead of her own, she begins suffering from violent visions about the young butcher's daughter, who lived there during the 1930s and helped a Jewish dissident hide from Gestapo in the cold room of her father's shop. However, not only was her father a violent staunch Nazi supporter and Party member but he also raped her on nightly basis. Carla slowly loses the ability to separate these horrifying visions from reality and begins to fear her own father. Hugh tries to help her but things only get worse. Is Carla slowly losing her mind or are the visions trying to tell her something?
