Shaun (Simon Pegg) is a 30-something loser with a dull, easy existence. When he’s not working at the electronics store, he lives with his slovenly best friend, Ed (Nick Frost), in a small flat on the outskirts of London. The only unpredictable element in his life is his girlfriend, Liz (Kate Ashfield), who wishes desperately for Shaun to grow up and be a man. When the town is inexplicably overrun with zombies, Shaun must rise to the occasion and protect both Liz and his mother (Penelope Wilton).
It’s just one of those days when you’re feeling a little…dead.
