A young American-born Muslim offers a silent prayer to Allah before getting up from his seat on a bus just outside Washington, DC. He leaves behind a backpack. Within minutes, the bus explodes near the Pentagon. The largest attack in the United States since 9/11 paralyzes the country. The FBI quickly identifies Hassan al-Zaid as the primary suspect. A search of his home reveals bomb-making equipment and a taped confession in which he pledges allegiance to as-Sirat, the world's most dangerous terrorist group, and its elusive leader Omar Bashir. Before the massive manhunt even begins, Hassan al-Zaid manages to slip out of the country. But a special unit of CIA terrorist hunters is on his tail and follows him across four continents to Pakistan. Once there, a member of the team discovers that as-Sirat is just days away from carrying out a nuclear attack on the United States. Having lost all ways to communicate with the rest of the unit, he has to risk everything to relay the information back home and stop the terrorists from carrying out their plan.
