Czarna Dama

Two brutal murders shocked a private boarding school: the girls were found in the woods with their throats cut. The students are convinced – it is the work of the ghost of the Czarna Dama, a local legend known to all the residents in the area.
After learning from a wealthy client that mysterious and dark events began to repeat themselves after thirty years, the IIN team takes on the case. The researchers must find out if the ghost of the Czarna Dama is really that dangerous? Perhaps the evil is much stronger and more extensive than the tormented, lost soul?
