William Castle's gimmick-laden horror thriller is a fairground fun house come to life. Vincent Price stars as a suave eccentric millionaire married to a beautiful and greedy gold digger. Together they are hosting a party in a sinister haunted house. Five guests are invited to spend the night and each will get $10,000--but only if they survive until morning. The doors are locked at midnight. Will you make it out alive?
