On the busiest shopping day of the year a number of idealistic students are about to carry out an eleborate media stunt which they believe will cause chaos at the checkouts. But the plan has gone terribly awry and instead, their backpacks are stuffed with explosives and poeple lie dead in the country's biggest mall.
A white collar group called Citizens of American Pride is accused of the massacre but insist it was the work of rogue members. Caught up in a political nightmare, battling a new interim director and mourning the death of her boss, A D Cunningham, FBI profiler Maggie O'Dell must put her troubles aside to find out who is behind the attack.
Along with security expert Nick Morelli, Maggie follows the trail for answers until an anonymous tip revelas one of the students is her own brother, Patrick. Afraid and on the run, Patrick has to decide whether he can trust Maggie enough to help her unravel this horrifying nightmare.
