A box is left at a police station containing a notebook and polaroid photos of bound women. The notebook and photos reveal the work of a serial killer.

The names of the women are written on the back of the photos. These names match unsolved cases. Thanks to the discovery of the box, we know that these women were kidnapped by the same man.

Gain access to the police files of Merel van Der Vliets, Britt Kooymakers, and Samira Bachuma, investigate the clues, and unmask the killer.
