A bank executive receives a bomb threat while driving his children to school that his car will explode if they stop and get out.

When a mysterious caller puts a bomb under his car seat, Matt Turner (Neeson) begins a high-speed chase across the city to complete a specific series of tasks.

With his kids trapped in the back seat and a bomb that will explode if they get out of the car, a normal commute becomes a twisted game of life or death as Matt follows the stranger's increasingly dangerous instructions in a race against time to save his family.
