It's shaping up to be a good weekend for Jason, a shy teenager. He's driving up to a cabin in the woods with his brash best friend Colin, Colin's older sister Summer, and their father and stepmother Roger and Lisa, who are permanently stuck in party mode. But things quickly go south when Jason, Colin and Summer witness their neighbor feeding two locals to her undead husband and kids. Realizing their own potential fate, the kids must work together to bash in some zombie skulls and save themselves from the neighbor's ghoulish family.
