Transit (2012)

Just out of prison, Nate needs to regain his family's trust, so he takes them on a road trip. His plans take a nasty turn when a group of criminals covertly stashes $4 million from a deadly bank heist in his car with the aim of collecting it once it gets through a police roadblock up ahead. Nate's family completes their unknown task and speeds off down the highway, but the criminals need their money and will stop at nothing to reclaim it.
