Isabel Eriksson was drugged and kidnapped by Dr. Martin Trenneborg during their second date. When Isabel then woke up, she found herself in a bunker, which Martin Trenneborg had spent several years building. In the documentary Bunkerkvinnan, she tells her story and returns to a bunker, reconstructed like the one Martin Trenneborg had built. Isabel suffers from a severe form of post-traumatic stress disorder as a result of the kidnapping, which prevents her from living a normal life.
