A discovery from TMDB

Carnival Evil

Five strangers are abducted. They awake to find themselves in an apparently abandoned carnival. One by one, they are each tortured by a mysterious man and his two associates who use the carnival rides and games to painfully kill. The kidnappers film their whole ordeal as the captives ponder why they have been selected as victims. Finally, the last survivor discovers the common bond that sentences them all to their fate.
