Shaun of the Dead

Shaun (Simon Pegg) is a 29-year-old electronics shop salesman with no direction in life. His younger colleagues don't respect him, he has an estranged relationship with his stepfather Phillip (Bill Nighy), and his housemate Pete (Peter Serafinowicz) is fed up with Ed (Nick Frost), Shaun's vulgar, unemployed best friend. Furthermore, Shaun's girlfriend Liz (Kate Ashfield) is unhappy with their social life as they spend every date at Shaun and Ed's favourite pub, the Winchester. Because Shaun always brings Ed, Liz is always forced to bring her flatmates, David (Dylan Moran) and Dianne (Lucy Davis). Shaun promises Liz that he will change.
After a bad day at work, Shaun forgets to book a table at the restaurant he promised Liz they would go to, to (belatedly) celebrate their anniversary. When he suggests the Winchester for the date, an angry Liz breaks up with him. Shaun drowns his sorrows with Ed at the Winchester. As the two head home at 4am to play music, an enraged Pete â suffering from a bite wound he received earlier â confronts Shaun on his flaws, telling him to sort his life out.
The next morning, a zombie apocalypse has overwhelmed the city, but Shaun doesn't notice due to his hangover. He and Ed encounter two zombies in their backyard and learn more about the outbreak by watching the news, before heading outside to kill the two zombies (and another that walked through the front door) with blows to the head. They briefly discuss a plan to rescue Shaun's mother, Barbara (Penelope Wilton), and Liz, then wait out the crisis in the Winchester.
Shaun and Ed escape in the now-zombiefied Pete's car and pick up Barbara and Phillip, who has been bitten. They head over to Liz's flat to collect her, with Diane and David reluctantly tagging along. On their way to the Winchester, Phillip makes peace with Shaun, dies from his bites, and then reanimates. The group abandon the vehicle and continue on foot. The streets surrounding the pub are overrun, so the group pretends to be zombies to sneak past them. Outside the Winchester Shaun gets into an argument with Ed which alerts the zombies; Shaun leads the horde away while the rest take refuge in the pub. Shaun rejoins them after giving the zombies the slip.
Several hours later the zombies return; Shaun discovers the Winchester rifle above the bar is functional and the group uses it to defend themselves. Barbara reveals she was bitten along the way and dies after giving Liz her locket and implying she approves of her and Shaun, and a distraught Shaun is forced to shoot her after she reanimates. David is then pulled through a window and torn apart by the zombies, while Dianne rushes out to rescue him, disappearing into the advancing horde. Pete arrives as one of the zombies and bites Ed but Shaun shoots Pete and sets fire to the bar. The fire spreads, setting off the remaining rifle ammunition while the remaining survivors, Shaun, Liz and Ed, flee into the cellar and contemplate suicide. Discovering a barrel hatch elevator that opens to the outside, Shaun and Liz escape on the elevator as a wounded Ed volunteers to stay behind with the rifle. Back on the street, the British Army arrives and guns down the remaining zombies, rescuing the two.
Six months after the outbreak, civilization has returned to normal, with the zombies now used as cheap labour and entertainment. Liz and Shaun have reconciled and moved in together, and Shaun keeps the zombified Ed tethered in the backyard shed so they can play video games together.
