For a rookie cop, there's one thing more dangerous than uncovering a killer's fantasy. Becoming it.

When a psychotic Wall Street broker witnesses rookie cop Megan Turner gunning down an armed robber in a grocery store, he becomes instantly obsessed with her. In the midst of all the swift and sudden violence, he manages to steal the assailant's gun; as a result, the novice cop, who already has more than one strike against her because she's a woman, is suspended for using excessive force and killing an unarmed man. Soon thereafter, the broker arranges a "chance" meeting with the now vulnerable policewoman, and the two strike up a romance. Meanwhile, he is carving her name onto bullets and using the stolen gun to go on a brutal murder spree.
