In England a new performance drug is tested on 30,000 people. One month later, they start going crazy. Then, they start changing. There's an effective scene where a transformed person--covered in black veins and difficult to kill--attacks the doctors. The main character is bitten--but he only has enough medicine to keep the infection at bay for a while. All the characters converge at an auto garage, battling off the zombies. People get bit, fight among themselves and a guy shoots himself in the head rather than become a zombie. Overall, this is just another unremarkable zombie movie that blends in with a hundred others.
