Arthur Banks (Kiefer Sutherland) is an Ivy League-educated hitman for Latin American drug cartels who picks up solitary women, uses them as cover for a hit, then kills them. His trademark is a bullet with a tungsten core. Over the years, he has become wary of the FBI's attempts to catch him, including by use of satellite and security cameras, which leads him to mostly stay in rural desert areas when not working. The FBI team is spearheaded by Agent George Scanlon (Jamey Sheridan), who lost five years of his career when Banks killed a witness he was guarding 15 years ago while leaving no evidence behind. In a desperation sting, Scanlon plants Agent Bennie Harper (Melora Walters), portraying a drifter, in Banks' path, and Banks picks her up for what he says will be his last job, a hit on a Mexican presidential candidate. Scanlon and Agent Donna Marbury (Leslie Stefanson), along with several support agents, follow Banks and Harper through the Southwest, but the scheme goes wrong when one of the tailing agents is spotted and caught by Banks.
