With the school board threatening to pull their funds, Janine and Gregory decide to help Ava out with her presentation in front of the Superintendent. However, their plan is derailed when a curveball is thrown at Ava. Meanwhile, Barbara offends Melissa when she doesn’t agree with her blackmail idea.

Barbara organizes a candy-selling fundraiser to raise money for a school field trip to the science museum. When sales don’t go as planned, Ava steps in to teach the students new, unconventional selling tactics. Elsewhere, Mr. Johnson and Jacob butt heads about how to take care of a cat found in the janitor’s closet.

When Barbara's church choir uses the gym for rehearsals, Ava notices tension in the group. Jacob's eagerness for a full social calendar worries Gregory. Melissa and Janine investigate a new substitute.
