Dawn of the Dead

The Police and the National Gaurd find themselves fighting a losing battle on two fronts as they remain unable to curb the growth of the zombie menace and people refuse to be evacuated from the cities. With matters getting worse and the authorities losing control by the hour, two members of a Philladelphia SWAT unit, Roger and Peter, decide to get out of the city before the zombies finally take over. Hooking up with their freinds Steve and Francine, who have swiped a helicopter from the TV station where they work, they fly off cross country towards Canada, in the hope of finding somewhere secluded to set up camp. On the way, they come accross a giant out-of-town shopping mall which has been abandoned. Deciding it would be a good place to hold up, they set about barricading the doors, sealing off all the entrances then wiping out the zombies still inside. But having survived inside the building for several months, their peace is shattered when a gang of marauding bikers show up to try and loot the mall. As soon as the bikers re-open one of the secured entrances, the Zombies move in and a bloodbath ensues as the two sides clash quite spectacularly, with the besighed 4 stuck in the middle.
