Throughout the film, the main overall theme is that a woman had an illegitimate daughter with someone while she was married, her husband left her, and she was alone with three girls and the youngest, Tita, was to never marry because she was to take care of her mother until the day she died. As Tita grew her and a boy, Pedro, fell in love, but her mother would not allow her to marry, and instead, he married her sister, Rosura, to be close to her. Pedro and Rosura had their last child and Rosura vowed she would not be able to marry because she too, like Tita, would have to take care of her until the day she died. Tita very much hated this idea, as she hated how her mother controlled her and forbade her to not marry her only love, as seen at the end when Rosura dies, Pedro and Tita are now able to get married at last.

The mother was in charge of her daughter, she said she was not to marry and she did not. Then the sister wanted to follow through with the same tradition that had made her sister so miserable.
