Alex ("The Beach") Garland's first screenplay is a terrifying page-turner brought vividly to the screen by director Danny ("Trainspotting") Boyle. A virus that locks those infected into a permanent state of killing rage is accidentally released from a British research facility. Twenty-eight days later, a motocycle messenger awakes from a coma and finds himself among a small group of survivors in London, trapped in a desperate struggle to protect themselves from the infected. As they attempt to salvage a future from the apocalypse, they find that their most deadly enemy may not be the virus, but other survivors.
