When you enter the big top at Phobius Haunted House in search of curiosities and entertainment, you get more than you bargained for. Instead of the traditional tightrope and car full of clowns, Phobius hides darker secrets. Behind the curtain, Dr. Fears works on ghastly experiments. He started by dissecting the body of the strongman in an attempt to develop an elixir that would erase all fear. Unsuccessful, he now applies his experiments to unsuspecting patrons who come to the carnival. Patients who survive become part of the carnival themselves, luring more audience members backstage for a special treat.
