The Dead Inside (also known internationally as Infected) is a 2013 British independent horror film directed by Andrew Gilbert.

The large ensemble cast features David Wayman, Simon Nader, and Luke Hobson as survivors of the outbreak who barricade themselves inside a village high school.

After an unexplained virus causes the reanimation of the dead, a group of civilian and British Army survivors barricade themselves inside a village high school.

The Dead Inside was filmed over approximately four months, from late 2010 to early 2011, in the English counties of Bedfordshire and Buckinghamshire.
