Episode 219 "Frozen Faith"

The Office of Scientific Investigation and Research (O.S.I.R.) investigates a suburban home in which the living room has become an icy chamber. The team de-ices the door, and enters the room, where it discovers a teenaged boy sitting frozen in an armchair. Dr. Anton Hendricks (Colin Fox) and Case Manager Matt Praeger (Matt Frewer) take the boy, Henry Bruna (Patrick Thomas), upstairs to submerge him in a warm bath. Downstairs in the kitchen, Chief Data Analyst Lindsay Donner (Nancy Anne Sakovich) interviews Henry's grandmother and the owner of the house, Mrs. Cynthia Bruna (Helen Hughes). Cynthia is the sole guardian of Henry whose parents were killed in a car crash. Cynthia's husband (Joe Botond) died two weeks ago, but Cynthia tells Donner she's glad he's dead. She also tells Donner the temperature in the house started dropping as soon as he died. Upstairs, as Hendricks revives Henry in the warm bath, the boy begins speaking in a deep, adult voice. When he asks Hendricks to "save him", the bathroom door flies open in a frigid blast of air. Henry then grabs Hendricks and kisses him on the forehead, sending Hendricks into a trance-like state. Suddenly, the adult presence leaves, and Henry is back to a frightened teenager, shivering and crying in the bathtub. As Praeger tends to Henry, Hendricks leaves the house, stopping to tell Cynthia the boy will be fine. Then, in a gesture that horrifies Cynthia, he takes her head in his hands and kisses her on the forehead.

Outside in the mobile lab, Chief Science Analyst Peter Axon (Barclay Hope) tells Praeger he thinks that a haunting is taking place at the Bruna house. Hendricks, strangely dressed in a thick winter parka, joins the conference. Praeger orders the team to conduct further interviews. Hendricks talks to Henry who can't remember anything about being in the freezing room. When Hendricks begins to speak to him in German in the familiar voice of his grandfather, the boy bolts from the room, terrified. Hendricks begins to act strangely around the rest of the team, making bizarre comments and trying to turn the investigators against each other. Then he confesses to Axon that he visited a prostitute when he was a young man, an act totally out of character for Hendricks. Praeger asks Dr. Claire Davison (Soo Garay) to examine Hendricks. She too becomes very worried about Hendricks' behaviour and warns that he is showing signs of psychosis. Shortly after the examination, Hendricks disappears.

The team searches for Hendricks, who wakes up in a homeless shelter, disoriented, his pants soaking wet. He reads in the paper that a prostitute was drowned, and fears he may have been involved. As he leaves the shelter, he meets a priest, Father Carlisle (James Mainprize), and spits in his face. He tells the priest he is not who he appears. Meanwhile, the team finds out that Bruna was being blackmailed by a man named Martin Stossel. But Hendricks find Stossel before them, and confronts the blackmailer as he swims laps in an indoor pool. Hendricks pushes Stossel's head under the water, as Stossel, terrified, sees Bruna in Hendricks' face. Stossel manages to swim away, and Hendricks leaves the building. He then enters a church, where he finds Father Carlisle. Father Carlisle gives Hendricks sanctuary and finds Praeger to tell him that Hendricks is possessed by an evil byon. He tells Praeger he needs the name of the beast in order to perform an exorcism. Praeger is skeptical and wants to pursue other reasons for Hendricks' strange behaviour.

Axon and Donner find Stossel, who tells them that Bruna was really a Nazi named Gunter Hoffner who murdered hundreds of Jews. Hoffner would pretend to baptize his victims in a river, then would drown them and let their bodies float away. Axon and Donner tell Praeger they're convinced that the evil Hoffner is possessing Hendricks. Praeger goes to Father Carlisle for help only to discover Hendricks has escaped from the church. Praeger returns to the Bruna house to find Hendricks in the frozen living room. Praeger confronts the byon in his lair, while upstairs Cynthia Bruna drowns herself in the bathtub. Praeger finally tricks the byon into revealing his name and Father Carlisle arrives to perform an exorcism. Hendricks is freed from his possession, but does the byon live on in the body of the priest?
