Patricia Carroll was once engaged to Stephen Trefoile who died in an auto accident. Now in England to marry her new fiancé Alan Glentower, she decides to follow up on a promise and visit Stephen's mother. Mrs. Trefoile welcomes her warmly and insists that she spend the night. She proves to be a demanding hostess however - there are no mirrors in the house, insists that Patricia not wear lipstick and is highly religious requiring that her guest attend prayers with her. When Mrs. Trefoile tells her that she considers her to be her daughter and that it would be a sin to "remarry", Patricia tells her the truth: that she never intended to marry Stephen. Mrs. Trefoile then locks her in a room, intending to teach her the errors of her sinful ways.—garykmcd
