It's 18th century France and a man is on an obsessive quest to discover the man responsible for his beautiful sister's murder. He will grapple with conspiratorial intrigue and encounter many men whose political sway is propelling the French revolution, but nothing can compare to the mysterious source of mystical power that lies at the heart of his quest - a power so great that his own sister's soul will return from the afterlife and enter her own brother's body to help solve the mystery. ~ Cammila Albertson, All Movie Guide
