Dead*Line (2008)

Seth is an ex-con who desires one thing: revenge upon the abusive guard who tortured him in prison. Hollis is a guard who believes he properly delivers 'God's justice.' Now exonerated, Seth confronts Hollis at a remote diner all the while experiencing harrowing flashbacks from Hollis' treatment. His plan: to execute Hollis at the very time he himself was sentenced to die. As the minutes pass, Seth's purpose, his motives, sense of self, even his reality will be drawn into question. One thing is certain - someone will die when the deadline comes.
