Animal rights activists free a group of infected chimpanzees to horrifying results in this speculative sci-fi horror effort from writer Alex Garland and director Danny Boyle. Waking from a coma in a deserted London hospital 28 days later, bicycle courier Jim (Cillian Murphy) takes to the deserted city streets in a state of mystified confusion. Joining forces with another group of survivors following a terrifying encounter in a seemingly abandoned church, Jim soon learns the truth behind the deserted streets and the menacing creatures that lurk in the shadows. It's soon revealed that the chimpanzees had been harboring a deadly virus that sends its victims into a furious, murderous rage, and in the days following the initial exposure, the entire population was nearly wiped out due to the resulting homicidal rampage. Is there still a glimmer of hope for humanity -- or has the deadly "rage" virus found its way to foreign shores and infected the entire planet?
