During Christmas vacation, a majority of the School Girls are leaving for Christmas vacation, however some are staying including Nancy, Melody, Leia, Trisha, Sam and Cynthia. Mrs. Jensen walks into a room with a framed photo of Mrs. Jensen's Daughter on a desk and a list of names written on it. She then takes a red marker and crosses out the names. Mrs. Jensen tells the girls that Mrs. Calvin will be gone for the weekend. Mrs. Jensen walks back in with pie and asks where Cynthia is and Leia tells her Cynthia wasn't feeling well and went to bed. Mr. Ronsoni stops by with a cannoli and tells Mrs. Jensen that the doctors will have to perform a bypass on her. Leia runs in and tells Mrs. Jensen that her and the others have decided to do all of the cleaning up so she can go to bed. Mr. Ronsoni calls Ralph creepy as he walks away and then calls the students rich bitches. As Leia is leaving she purposefully mispronounces Mr. Ronsoni's name. Mr. Ronsoni leaves after telling Mrs. Jensen she should do more with her life. Nancy gives Mrs. Jensen some milk. The next morning, T.J. tells Mrs. Jensen that his plane needs to be repaired and then he and Alex will leave. Polansky arrives with Jim and Dan to investigate the murder of Ralph. Polansky tells them he is going to leave Jim and Dan to watch the place and that everyone is to stay indoors. Polansky leaves after calling Mrs. Jensen by her first name. Leia argues with the others and tells them that everyone that is missing will come back. Nancy and Alex tell Mrs. Jensen that they are worried for their safety, but she tells them they should be safe with the police hanging around. Nancy and Melody find Leia dancing outside in a crazed trance. The person in the Santa costume tries to stab Melody and she runs away, leaving Nancy and Leia. They remove their Santa mask, revealing themselves to be Mrs. Jensen. Mrs. Jensen blames Nancy for killing Mrs. Jensen's Daughter, even though Nancy wasn't enrolled at the school yet. Nancy hits Mrs. Jensen in the head which knocks her unconscious. Mrs. Jensen goes searching for Nancy and Nancy goes out to the balcony that Mrs. Jensen's Daughter fell from. Mrs. Jensen lunges at Nancy and falls off of the balcony to her death.
