It's been seven months since the zombie plague that devastated Britain in "28 Days Later..." and all is well. Or is it? An infected person manages to enter the U.S. Army-controlled safe zone in London, unleashing an even more dangerous strain of the virus. When all attempts to contain it fail, a small group of survivors is forced to flee for their lives. Robert Carlyle, Rose Byrne, Jeremy Renner, Harold Perrineau, and Catherine McCormack star.
