Marie Morgan has been lured to an old abandoned house by a false note from a friend, and is in jeopardy although she doesn't yet realize it. As she sits at the table inside, she thinks back to the banquet held there 13 years earlier, when she was a little girl. Only 12 of 13 guests had attended, and the manor's owner, the Morgan family patriarch, who was then dying, has since passed on. The chance to claim the bulk of the estate fortune has resulted in an ongoing campaign of murder by someone targeting the original 12 guests, whose dead bodies are being left at the table in the same seats they had occupied originally.
The film was a box office success and received mostly positive reviews from critics. Variety called it "vastly superior" and "a positive money maker".[4]
