In Jupiter, Florida in 1951 Elsa Mars rents a farmer's field and sets up the tents for her circus freakshow. She's always on the lookout for new acts and visits the Tattler sisters, Bette and Dot, who are hospitalized after the local milkman finds their mother dead on her kitchen floor. The sisters are perfect for Elsa's show - they are Siamese twins with two heads sharing one body. Elsa sees them as her new headliners. Other acts include Ethel Darling, the bearded lady and her son Jimmy, the Lobster Boy. They group is clearly not welcome in the community and few people are coming to their nightly show. Meanwhile a clown by the name of Twisty is killing people. He's also taken a young boy and a young woman prisoner.
