First, Charlie's little brother is pulled onto the tracks of a oncoming train by an unseen force. Several days later, his father is killed by a bizarre garage-door malfunction. Both times Charlie is present -- watching.

Charlie's Romanian grandmother thinks that he is responsible for the deaths. A firm believer in old-world traditions, she calls in the ancient Calusari to perform the rituals needed to cleanse the boy's soul.

But is Charlie truly a demon? Or is there a darker, more horrifying force at hand? FBI agents Mulder and Scully must find out -- before a young boy becomes the final sacrifice!
