A government agent must ferret out his arch-enemies in this action thriller. The Brotherhood of Liberty, a right-wing militia group dedicated to the violent overthrow of the U.S. government, has stolen three special Air Force missiles whose warheads have been loaded with biological weapons powerful enough to kill the population of a large city in a matter of days. ATF agent Ethan Carter (Dean Cain) is assigned to go undercover as a Brotherhood of Liberty member to find out what became of the missiles and what the militia intends to do with them. Working with Wilson Fain (Frederic Forrest), a former BOL member who has been released from prison on the condition of co-operating with the ATF, Carter comes in contact with Brotherhood leader George Armstrong Montomery (Stacy Keach) and learns of the group's shocking plan to seize power. Meanwhile, ATF trainee Julia Sanders (Jennifer Beals) is assigned to watch out for Carter and keep him out of danger, though there's little she can do to save him after he's dug himself into the Brotherhood.
