Isabel Eriksson, an alias used to protect her real identity, was targeted by Dr Martin Trenneborg, who gave her strawberries laced with the date rape drug Rohypnol, as part of his twisted plot in September 2015. He then drove her 350 miles from her Stockholm flat to a remote farm in southern Sweden where he planned to keep her as a sex slave.

Speaking in court in 2016, Isabel said that Trenneborg chillingly told her that the door was built like a 'bank vault' and she would 'never be able to open it'. 'Then he asked me if I had any wishes, whether he should expand the bunker, [..

.] because I will be living here for many years,' she added. Now Isabel, who was working as an escort at the time, has opened up about the whole terrifying ordeal in a new documentary.
