The adventures of relatable and adventurous Riley Matthews, the tween daughter of Cory and Topanga Matthews, and her bold best friend Maya as they traverse the twists and turns of teenage years at Manhattan's John Quincy Adams Middle School where Riley's dad is their History teacher.
When Maya’s artwork is featured at a school event, Riley sees it as an opportunity to help Maya mend her relationship with her mother. Meanwhile, Cory and Topanga get a surprise visit from their childhood friend Minkus.
When Smackle, a debate champion from another school who happens to have a crush on Farkle, realizes that he only sees her as an academic rival, she enlists Maya and Riley to give her a makeover.
Cory gives the class a living-history assignment that takes the four friends back to New York City in 1961.
Cory divides his class into two fake companies for a lesson, one driven by profits and the other by making people happy. Meanwhile, Riley and Maya encounter a lady in the subway who is quite different than they first perceive her to be.
The kids face a trilogy of terror when Riley has a sleepover at Maya's with her Gammy Hart and pet ferret. Auggie confronts the monster under his bed, and Farkle tackles his most terrifying fear yet - playing softball.
When the kids are assigned a special lesson on appreciation, Riley and Maya are forced to work in the school cafeteria while Lucas and Farkle are assigned janitorial duty.
