Gideon Davis has settled into the quiet life of an academic and is weeks away from being married when he discovers evidence of an impending terrorist attack on U.S. soil. He brings his suspicions to his ex-girlfriend, FBI Agent Nancy Clement, but her bosses are leery of the meth-head informant affiliated with a white supremacist group. Both Gideon & Nancy become increasingly convinced that a serious plot exists, & they, along with Gideon's brother Tillman, race against time to stop the attack.
