Miss Nelson is Missing

Miss Nelson is Missing is an upcoming 2018 animated mystery comedy film based on the children's book of the same name by Harry Allard.

Plot
Miss Nelson is a grade-school teacher whose students constantly take advantage of her nice nature. After their constant misbehaving and rudeness, and their refusal to learn, Miss Nelson determines something has to be done. But then one day, she does not come to school. The students decide that, without a teacher, they can misbehave all day. However, before they get the chance to make mischief, a substitute, Miss Viola Swamp, shows up. Swamp is a strict disciplinarian and gives the students significantly more school work than Miss Nelson ever did. The contrast between the two teachers is so great that the students actively go looking for Miss Nelson and make unlikely conjectures about what may have happened to her, including some students who go so far as to fill out a missing person report with the local police. After many days of tyranny under Miss Swamp, Miss Nelson returns to class and the children rejoice, now being more respectful of her. At the end of the film, it is revealed that Miss Viola Swamp was Miss Nelson in disguise, and a police detective has called off his search for Miss Nelson and will now look for this enigmatic Miss Swamp.
