A deadly virus sweeps across the planet, turning anyone it can infect into a flesh hungry monster. Supermarket manager Howie and one of his employees, the unassuming shelf-stacker Dave, who just happens to be an ex-special-forces killing machine, team up to survive the apocalypse. As Howie and Dave collect an assortment of survivors, Haywood injects a heavy dose of gallows humour and proper geezer bants into the full speed ahead bloody mayhem.
