The Human Centipede 3

An insane prison warden and his sidekick hatch a plan to simultaneously cut costs and deter prisoner revolt in their overpopulated, underfunded jail. Inspired by Tom Six’s outrageous horror franchise, the warden selects not three, not twelve, but five hundred of the most violent, depraved, psychotic inmates to be joined ass-to-mouth, creating the world’s first prison human centipede!
