In the debauchery of late-1970s Louisiana, Tobias awakens from a coma with no memory of how he came to this torrid Southern hamlet plagued by a spree of deaths and steeped in supernatural folklore. Deliciously tormented by demonic fantasies and subsequent blackouts that his doctors can't explain, he teeters on the edge of lunacy. Rising panic leads him to Madam Genevie, a beautiful soothsayer yearning for a mysterious man she can't yet have and harboring a dark secret. Genevie is an immortal psychic vampire, a succubus that feeds off the life force of others. She emits a sensual allure that Tobias is helpless to resist, even if it kills him. Seeking answers while falling into this dangerously passionate lust, Genevie discovers a seductive entity possessing the locals, a Legion of psychic vampires on its tail, and the sacrifices she must make to be with the elusive man she loves.
