Death Race 2 (2010)

A crime boss hires Luke to help coordinate a robbery.  But when the guys with him screw it up, Luke ends up killing a policeman.  After a car chase, he is caught and sent to jail, where he becomes the protector of Lists, a nervous nerdy kid. Why was Lists sent here?  Everyone else is a hardened criminal that could bash your face in with a rock, while Lists is the pasty kid who plays Dragons and Dungeons with his nerd friends on a Saturday night.  Seems like he got a raw deal.

The prison broadcasts pay per view events called death matches, where caged prisoners fight to the death.  But when a riot breaks out, the warden pulls the plug.  The announcer comes up with an idea for Death Races, a three day event with the prize being a release.

The crime boss is afraid Luke will talk at some point, and puts out the word that he'll pay a bounty to anyone who can kill Luke.  Most of the other cars in the race are trying to take him out.  So when Luke burns up in his car, everyone thinks he's dead. But then the mysterious Frankenstein shows up to race like no one has ever raced before.  Mediocre at best.
