The Movie Insider

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 small group of survivors are trapped in London, caught 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 is not the virus, but other survivors.
