Four teenage friends spend the night in a carnival funhouse and are stalked by a deformed man in a Frankenstein mask.
Rebellious teen Amy (Elizabeth Berridge) defies her parents by going to a trashy carnival that has pulled into town. In tow are her boyfriend, Buzz (Cooper Huckabee), and their friends Liz (Largo Woodruff) and Richie (Miles Chapin). Thinking it would be fun to spend the night in the campy "Funhouse" horror ride, the teens witness a murder by a deformed worker wearing a mask. Locked in, Amy and her friends must evade the murderous carnival workers and escape before it leaves town the next day.
