Sarah Booth has a perfect distraction, however, in the form of the Black and Orange Halloween ball her best friends are throwing in New Orleans. Sarah Booth plans to dance the night away to the swinging tunes of her old flame Scott Hampton's blues band. But just as the party gets going, Scott receives a mysterious message that threatens his life and the lives of his bandmates.
