A soldier, Bart Gregory (David Anders of Alias, Heroes), gets shot in the head in Iraq when he thinks he runs over a small child on a desert road. His corpse is shipped back to Los Angeles for his funeral. But before they bury him in the ground he awakens, an obvious zombie, and goes to his best friend, Joey's, house. He freaks out. They go to the hospital and he explains how he's dead--and even shows the doctor his white eyes (and there's a clear bullet hole in his forehead!). The doctor is dismayed--and calls security-- when he takes off his shirt to show the autopsy scars. When he begins getting hungry he discovers that he needs to consume blood, like a vampire. Joey, feeling guilty tells him that he had slept with is fiance after his funeral--and he accidently kills her when he comes to visit. Eventually Joey becomes infected and one of the undead, which leads to further complications. He's later dismembered by a gang banger they attacked and killed (the zombies come back if you don't decapitate them before they awaken), so he's just this living-dead head.
This movie tries to be funny like Shaun of the Dead, Dead Heads and Arrgghh! Zombies! but can't quite pull it off.
