The film will follow four escaped convicts - Theodore, Vinnie, Darren, and Jacob - who must survive a zombie apocalypse in the UK. It will run 85 minutes with a small British budget and crew. The film aims to be original by pitting the survivors against each other as well as zombies. Mark Strong will play the antagonist Ed Small, who pretends to help survivors but secretly feeds his infected family. Robert Sheehan, Joseph Gilgun, Vinnie Jones, and Sean Pertwee will play the escaped convicts.
