The most suspenseful thriller of the year explores just how far we will go to protect ourselves and our country. When a nuclear expert-turned-extremist (Michael Sheen, Underworld) plants devices in three separate cities, the country's counter-terrorism springs into action and captures him. 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!
