Twenty-eight days after a killer virus was accidentally unleashed from a British research facility, a small group of London survivors are caught in a desperate struggle to protect themselves from the infected. Carried by animals and humans, the virus turns those it infects into homicidal maniacs -- and it's absolutely impossible to contain.
Horror is central to the film's identity—fear, dread, and the threat of the infected drive the experience, with survival and atmosphere being the core focus. While it includes action and drama, horror remains fundamental rather than incidental.
Best for viewers looking for a scary and high-tension horror movie.
