American Heart (2008)

A zombie outbreak takes a small southern town by surprise. In the wake of destruction, a motley crew of survivors finds shelter in the local hospital. Led by the town's naive sheriff, a ditzy talk show host, a washed up actor, and two attractive teens must learn to live together and come out alive. But between bickering over dinner, surfing the Internet, and having sex with each other, can the gang find time to fight off the undead?
