The body contains marks of many needle insertions and burns from sulfuric acid, which appear to have been inflicted while the child was still alive. Five years later, Claudia is still unable to get over the death of her child and she is addicted to tranquiliizers. Inexplicably, the presumed dead daughter Angela calls her mother, saying that she is still alive and needs her help.

The tape shows what appears to be the murder or torture of a naked woman, and also footage of Claudia when she visited the derelict clinic. Visiting a theological expert at the university, the two begin to uncover a bizarre cult called The Nameless that is said to sacrifice children. The cult was led by a now-imprisoned man called Santini who believed in absolute evil, and created his cult which also links to Germany's Thule Society. A doctor who helped him was also arrested but was released for lack of evidence. To make matters worse, Claudia finds herself stalked by psychotic...
