When Nolan Bishop meets a seductive redhead at a dark club in downtown Shreveport, little does he know his soul will be gone as soon as she is. It doesn't take Nolan long to realize this succubus, who now haunts his dreams, is named Eva, and has taken something from him. Through the underground network of the supernatural in New Orleans, he finds out he has a mere 7 days to destroy Eva before he turns into something sinister and inhuman - a feral vampire. In a race against all that is holy, Nolan accidentally runs into Eva's identical twin, Charity. He begs for her help to find Eva with the intent to kill her - all while trying not to fall in love with Charity - and all in seven days.
