Halle Berry plays a 911 operator who gets a call from a girl (Abigail Breslin) trapped in the trunk by a kidnapper. Not only is this a nail-biting rescue, it becomes a police procedural as we watch the resources used to find the caller. Most of the time, the film makes smart choices that keep you involved and sometimes even wanting to scream at the screen. The filmmaking is sharp with some flashy editing touches and solid sound design. Even though the conclusion is a bit much, up til then, it’s a well-crafted, gripping ride.
