Summary: Carla Moran awakens one night to find herself being beaten and raped by an unseen presence. Terrified of what's happening to her, and shunned by friends and family who think she's lost her mind, she seeks help from parapsychologists. The researchers soon discover that evil spiritual force has been drawn to Carla and is responsible for the violent attacks. The question now, however, is how do they stop it? Based on a supposedly true story.
