Slaughter at Camp Swinelake (1970)

When a meat-delivery mix-up forces a pork-themed fat camp to kill and serve its longtime pig mascot for dinner, a swine-zombie outbreak emerges. An insecure camper must team up with her CIT bestie, her cruel, thin head counselor, her hunky crush, and her foul-mouthed little sister to escape so they won't be bacon by breakfast.
