England, 1892. When spiritual medium Beatrix Greene is approached by scientist James Walker with a job offer to conduct a seance, she fears he plans to expose her as a fraud.
Beatrix and a group of supernatural sleuths—including Sir Arthur Conan Doyle—arrive at the infamously haunted Ashbury Manor, where James awaits with secrets in tow.
When Beatrix is possessed by a very real spirit, the seance must go on. James is forced to reveal his true motives.
As the ghost’s intentions become clear, a treasure hunt begins. Beatrix and James find that being trapped together has a certain appeal.
A second seance leads to answers from the past. Amorous inclinations ensue.
Beatrix and James learn, too late, that their efforts were in vain: a darker evil threatens them all—and one of their number has unleashed it.
Someone pays the ultimate price for dabbling in the world of the dead.
As James and Beatrix attempt to flee the manor, his past comes back to haunt him.
