Arthur Conan Doyle arrives in Toronto to address a group about spiritualism. His first stop is to attend a seance with William Murdoch were the medium, Sarah Pensall, announces that a recently murdered woman wants Murdoch to know that she is buried in a shallow grave. Murdoch finds the grave; he also finds out that Pensell is a fraud who uses an accomplice to investigate potential participants in her séances.
Doyle recommends that the police have Pensall conduct another seance with the goal of exposing the murderer; however, Pensell starts by apparently channeling Murdoch's deceased fiancée, Liza. This leads Murdoch to request a private séance, where Pensell tells him things that only he and Liza could have known.
The dead woman's lover, Fredrick Waters is murdered next.
Murdoch has determined that Pensall is a fraud. As he approaches the truth he convinces her to hold a private seance for his key suspect, Conrad Hunt. Pensall pretends to be passing unsettling news from the spirit world and Hunt confesses to the murder of the young woman.
