When college kids hiking near an abandoned military industrial complex in West Virginia mysteriously disappear, special agent Janet Carter - earnest, honest, and fed up with the stifling chauvinistic environment at the Roanoke FBI headquarters - is called in to investigate. Unfortunately, there are no leads - it's as if the three just vanished into thin air. The authorities at the FBI are quick to write off the case as teenage runaways, and order Janet off the case - but not before she has the chance to speak with the father of one of the missing, Edwin Kriess. Kriess is an ex-"sweeper," a member of an elite CIA task force trained to track down and bring in rogue agents. To be a sweeper means to be expertly trained in the art of hunting and killing, and Kriess was not only a sweeper himself, but the agent in charge of training and leading the entire program.
