Joan Crawford plays the daughter of the town's founder, an uncompromising woman who rules her home with an iron fist and exerts her influence over the town she owns so much of.
The story finds a young lawyer attempting to get Della to sell a parcel of land to a government contractor who will bring lots of jobs to the town. He's invited to visit her home in the middle of the night and discovers her and her daughter living in a nocturnal world, sleeping during the day and going about their business during the night hours.
He finds the daughter intriguing and is lured into their world with subsequent visits. The relationship eventually takes on tragic proportions.
While not the most famous film in Ms. Crawford's career, she looks fantastic in it, and it does have some fun twists and turns. Also in the cast is Diane Baker in her second turn as Joan's daughter (Straitjacket) and her third time working with Ms. Crawford (The Best of Everything) and Paul Burke, fresh from his portrayal of Lyon Burke in Valley of the Dolls.
