Mrs. Tara is a strict substitute teacher trying to get through a new day with a new class. But almost immediately the students behave badly, laughing and making crude remarks. Their temporary teacher warns them that she will not tolerate such bad behavior. However, none of the students in this class seem to take Mrs Tara very seriously and she doesn't understand why... She goes through attendance and it seems almost every student has some snide remark to say to her. She scolds them and tries to get through attendance but their behavior continues. She moves onto trying to help the students finish up a previous lesson, but it seems like when ever her back is turned the whole class starts talking and laughing. She looks over her shoulder to tell them not to make fun of their classmate for needing help, but the class still laughs. Mrs. Tara stands and tells them that no one should be laughed at or made to be embarrassed in this classroom. The class settles down a bit for now. Moving on to the next lesson Mrs. Tara instructs the class to take out their pens but she drops all her pens in the process. She bends down to pick them up and the class laughs some more. She tries to ignore them but then she hears them taking pictures too. While she picks up her pens she scolds them for once again for laughing and playing, not knowing why they would find everything she does so funny. But then as she goes to stand back up, Mrs.Tara trips on her pants and falls right on her butt and she finally realizes why the class has been laughing all day - her entire butt has been showing to everyone!! Some how her pants slip below her butt and she never noticed that it was exposed to her class! She looks so horrified and she tries to pull her pants up but she can't get them over her ass. She begs them to not tell anyone but the class keeps laughing and takes some pictures of her humiliation. Shestands and tries to reason with them, finally realizing her bush has been showing too. Almost in tears Mrs Tara tries to cover herself but her shirt isn't long enough. She calls a sudden recess as she runs out of the classroom.
