Shaun (Simon Pegg) is a 30-something loser who splits his time between a dead-end job at an electronics store and the apartment he shares with his grubby best friend, Ed (Nick Frost). Shaun’s life takes a nosedive when his girlfriend, Liz (Kate Ashfield), dumps him, and his contemptible stepfather, Philip (Bill Nighy), shows up to scold him for not taking better care of his mother, Barbara (Penelope Wilton). But just when it seems things can’t get worse, the dead rise up to lay waste to the earth and all hell breaks loose. Shaun must summon his courage and prove himself once and for all by rescuing Liz and his mother. With his faithful roommate by his side, nothing—not even the flesh-hungry hoard outside his door—can stand between him and the two most important women in his life.
