In the wake of the tragic events at Waco, Texas where an armed conflict with armed militiamen broke out, agents of the federal governments Alcohol, Tobacco, and Firearms (ATF) carry out a clandestine mission within another militia operation that is possibly involved in the sales of guns and the murder of an agent. One agent infiltrates the operation against her directors orders. When events start unraveling and an FBI agent threatens to take over the operation and start a military action, the ATF agents have to apply what they learned from Waco to stop another bloodbath.
