Death seems to follow Clay Birdwell (Joaquin Phoenix), a small-town Montanan who tries to end an affair with a woman (Georgina Cates) after her husband — his best friend — commits suicide. But when fast-talking serial killer Lester Long (Vince Vaughn) forges a friendship against Clay’s will, the death toll climbs even higher. Now, a feisty FBI agent (Janeane Garofalo) has Clay in her sights as the prime suspect.
