John wakes up to find his girlfriend, Sara, dead on the bathroom floor in the middle of the night. Upon calling an ambulance, the 'fun' begins.

The tale of satanic vampire sorceress Eva, whose sexually-charged midnight rituals are interrupted when God-fearing local villagers burst into her lair and murder her. A century later, motorcycle-riding writer Lisa moves into the same cabin where Eva was executed, with the intent to write a book about the supposedly haunted spot's history. Soon, Lisa is having vivid, perverse dreams and slowly, surely, Eva begins taking over the young woman, using her body as a vessel to commit even more atrocities in the name of resurrecting an ancient monster from the underworld.
