Life is going nowhere for Shaun (Simon Pegg). He spends his life in his local pub, The Winchester, with his best mate Ed (Nick Frost), has issued with his Mum and neglects his girlfriend Liz (Kate Ashfield). When Liz dumps him, Shaun finally decides to get his life in order. He must win back the heart of his girlfriend, repair his relationship with his mum and face up to the responsibilities of adulthood. Unfortunately, the dead are returning to life and attempting to eat the living. For the newly inspired Shaun, this is just another obstacle. In the face of a full-scale zombie epidemic, armed with a cricket bat and a spade, Shaun sets out with Ed in tow, to rescue his mum and grudgingly his step-dad, his girlfriend and even more grudgingly her friends David (Dylan Moran) and Dianne (Lucy Davis) and take them to the safest most secure place he knows, The Winchester.
