But the location of his bombs remains a mystery. With time running out, FBI agent Helen Brody (Carrie-Anne Moss, "Disturbia") agrees to work alongside a mysterious interrogator known only as "H" (Samuel L. Jackson, "Lakeview Terrace), whose ruthless methods get results. But a power struggle develops between Brody, "H' and the terrorist, and what happens next is unbelievable and -ultimately-Unthinkable!
