Buried

“170,000 sq miles of desert. 90 minutes of oxygen. No way out.”

In Iraq, a convoy of civilian truck drivers is attacked by insurgents, and Paul Conroy (Ryan Reynolds) wakes up afterward inside a wooden coffin. He has a lighter and a cell phone with a battery that is running down, and the air in the box is running down with it. Rodrigo Cortés keeps the camera in there with him, so the only other people in the film are voices on the line, and the question is how much anyone will do for one man buried alone.
