A traveling storytelling troupe Jacob used to be in visits Abbott Elementary for a day of education and entertainment. Jacob can’t wait to share this part of his past with his colleagues; but when he realizes they think the performers are corny, Janine does her best to help him embrace his nerdy side. Meanwhile, Melissa struggles with the new normal of her combined second and third grade class.

Janine is thrilled to help introduce a new beverage to the cafeteria, but it ends up causing unexpected consequences for the students, teachers and school plumbing system. Elsewhere, Melissa clashes with her new aide, Ashley, who brings more disruption than help to the classroom.

It’s Halloween at Abbott Elementary! When a student steals a bag of candy meant to be given out to the kids at the end of the day and starts distributing it during school hours, the teachers band together to find the culprit. Meanwhile, Janine is invited to a Halloween party by an old friend and starts to reconsider her personal life.

Gregory is named Educator of the Year. Later, Janine deals with a difficult student, and it's revealed that Barbara hasn't completed her teaching requirements.
