The Numbers Station

Disgraced Black Ops agent Emerson (Cusack) is sent on a routine assignment to protect Katherine (Akerman) at a rural CIA broadcast station. But this easy job quickly becomes the most dangerous mission of his life as the station comes under attack from an unknown, but determined, outside force.
With communication lines in serious jeopardy, an unclear target and no means of escape, Emerson and Katherine seek refuge in the bowels of the bunker. As the enemy drills down ever closer to the two agents, they face a life-and-death struggle, from which finding out the truth is the only exit strategy.
