The show centers on FBI special agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson) who work on cases linked to the paranormal, called X-Files. In this episode, a photograph taken just before the death of a two-year-old boy yields evidence of some supernatural intervention which piques Mulder and Scully's curiosity. When another death in the family occurs, the grandmother of the remaining child requests the aid of some Romanian ritualists, named the Calusari, in order to cleanse the home of evil.
