Dawn of the Dead (2004)

In the first few minutes, Nicole is at her job at the hospital and you hear of a "special high priority case from some government place." She goes homes and shags her boyfriend Lewis. The next morning, the neighbor girl (zombified)comes into the house and bites Lewis, who dies because his Jugular was cut. Nicole frantically calls 911, but no one answers. Meanwhile, Lewis gets up and attacks her. She escapes through the window and drives off, and we are introduced to the utter carnage in the city. She teams up with a cop, and they take refuge in a mall with several others. Towards the end, they decide to try to make it to an island in one of the survivor's boats, so they soup up two shuttle vans in the parking garage and break through the crowd of zombies outside. In the town, one van tips over and the boat owner is killed. The others pile into the other van and peal away, but Nicole stops them to run back and get the keys from the guy's corpse. They make it to the boat, and they float away.
