Vincent Hunter vows to never return to the force, but when a serial killer everyone else thought was locked away resurfaces, he is compelled to come back. The new murders dredge up old memories and a past he'd rather stay buried. Samantha Walker is content with her life as a beat cop but at Vincent's urging, she finds herself undercover as a dancer and on the tail of a serial killer. She will do anything to prove she's more than just a pretty face, even if it means squelching years of longing for Vincent. Vincent is determined to catch the serial killer at all cost despite the fact that working with the beautiful cop is a serious distraction. As they work together, he gets closer to capturing Mr. X but not without having to face demons from his past and risking Sam being the next victim.
