When a zombie plague infects Camp Special Dude, a dude ranch for the mentally handicapped, a ragtag band of campers and counselors struggles to survive the night. Led by the indifferent, nun-chuck-wielding head counselor, Mac, and his wheelchair-bound sister Dale, the unlikely heroes fight their way off the mountain as, one by one, they're picked off and join the ranks of the walking dead. It's a campy stampede of blood, boobs and gore as some "very special" people show that they can kick some serious undead ass.
