At the turn of the 20th century the Metropolitan Police were overwhelmed with bizarre cases so they turned to outsiders including Houdini and Doyle, who collaborated with New Scotland Yard on some unsolved and inexplicable crimes.
Houdini, Doyle and Adelaide investigate when a nun from one of the notorious Magdalene Laundries is murdered. A witness claims that the murderer was a young woman tormented by the nun - but she's been dead for 6 months.
After a terrifying encounter with otherworldly beings, a man awakes in a field claiming that the aliens have abducted his wife. It is only after Doyle has his own encounter that the team discover what's really out there.
The team travel to Canada following reports of a homicidal poltergeist. They meet other paranormal experts and one of them, Thomas Edison, shows them his Necrophone with which he claims to be able to talk to the dead.
In a small town in Ontario, a minister wakes up to find everyone in his village dead, without any sign of violence. Was this retribution for past acts of evil, and if not, how else to explain why the man of God was the only one spared?
