A fanatical gunman has taken a top lawyer prisoner, and is demanding millions of dollars for his release—which brings FBI agent Cal Clayton to the office complex. On the surface it seems a simple hostage situation. Intuition, though, says the lawyer's very attractive secretary, who's presently wearing only panties, is hiding something important. But the secretary, Jessie, is a prisoner, herself, in an unexpected way, one that touches Cal's heart and divides his loyalties.

Add in a crazy-lady's visit that left Jessie both tearful and angry moments before the hostage-taking, a gunman who may not be what he seems, and a ransom of tens of millions of dollars. What happens next is anything but certain. But then, it is Friday the Thirteenth. And you know what people say about that.
