Two teenagers visit a carnival freakshow, where the owner, billed as the Freakmaster (Hansen AKA "Leatherface), presents them with five chilling specimens and reveals the stories behind them. He tells the tale of a baby in a jar in "Fetus," a young boy on a leash in "Midnight Snack," a mummy in "The Uninvited Guest," and some human remains in "Unspeakable." Each tale is more terrifying than the last, until, after the fourth tale, the Freakmaster refuses to continue. The teens refuse to leave until the fifth and final freak is exposed, and when it is revealed, the kids get the shock of their lives!
