Young Morrigan, the daughter of a local aristocrat, is full of innocence and life. Angus Wulfe is an eccentric and devious doctor who stalks her while he cultivates a plan to win her affection. Their two worlds collide in a grisly twist of fate when the Plague arrives on the shores of their town. With no cure in sight, and bodies dropping incrementally every day, the doctor uses his influence, along with his reputation in medical advances - stemming from his clandestine and macabre experiments-to manipulate Morrigan’s father.

In return for her hand in marriage, the doctor would save her life. Clinging to life, Morrigan begins to feel a change. Has the doctor cured her, or did her father make a deal with the Devil?
