1908: Regina, Saskatchewan, the railroad hub of the prairies, is booming. The foxtrot is the latest craze hitting the dance halls, and silent movies are all the rage. But it's the newest fad, séances, that intrigues Myrtle Vanhoff.

Myrtle is tired of the constraints put on her by her father, Reginald Vanhoff, a lumber baron, and her mother, Amelia. Her mother is determined to make her and her daughter's mark on Regina's burgeoning social scene. But Myrtle has other ideas. On a lark, the rebellious young woman convinces her twin brother, Leopold, to attend Madame Scarlatta's notorious séances. They find more than restless spirits. Someone murders a bereaved patron while everyone at the table is holding hands. Myrtle and Leopold are determined to find out who and how. A Regina police sergeant is appalled at Myrtle's unladylike interest in the murders. But Jonathan Chapman of the Royal North-West Mounted Police is intrigued. Jonathan joins Myrtle and Leopold in their search for the murderer. When Myrtle gets too close to the truth, the murderer targets her as the next victim.
