Down and out backup singer and celebrity ex-husband Kasper (Valter Skarsgård) is invited to compete in the Funhouse, an online 'Big Brother' style reality show. To rebrand his image and tarnished reputation, Kasper reluctantly accepts the offer. Together with 7 other C-list celebrities from around the globe he will compete for the prize of 5 million dollars. At first, the Funhouse is just as the name suggests, full of wild times, budding friendships, love connections and brewing rivalries. To everyone's surprise, the fun quickly turns into misery when the first challenge leaves one of the contestants brutally murdered.
