Katherine (AnnaSophia Robb), a girl who lost her father since childhood, was extremely rebellious during adolescence. Her bad behavior caused headaches for the school, her mother, and her stepfather. So, regardless of whether Katherine agreed or not, her mother insisted on sending her to Blackwood Boarding School, run by Miss Durreit (Uma Thurman). The school is located in a remote village, restricts students from talking to the outside world, and refuses to use the Internet. Its original intention was to educate and correct girls with serious problems. The next day, four other girls with bad records also came to the school. They will study with teachers of mathematics, literature, music, and art to create a brand new self. In a short period of time, the girls' talents in all aspects have been stimulated one after another, as if they have regained the favor of the god of fate. However, everything seems to be so weird again...
