Vijf werknemers van het carnaval worden op de dag voor Halloween ontvoerd. Vervolgens worden ze vastgehouden op een grote plaats bekend als Murder World. Ze hebben 12 uur om een moorddadig spel genaamd 31 te overleven. In het spel zijn er moordlustige maniakken verkleed als clowns, The Heads, die hen opjagen.
Nee, helaas is 31 nog niet beschikbaar op Netflix in Nederland.
