When Amy brings store-bought donut holes to the bake sale, she draws the ire of Gwendolyn, who uses her PTA authority to get Jane benched from the soccer team. Angered, Amy decides to run for PTA president against her. A meet-and-greet at Amy's draws only one visitor, who tells them Gwendolyn has launched a rival party at her own house, catered by Martha Stewart. The other moms and Martha swiftly abandon Gwendolyn's party when it becomes clear that she intends to lecture them all evening, leading to a successful party at Amy's house. Afterwards, Amy discovers that Carla had “booty texted” Jessie from Amy’s phone. Jessie forgives Amy and asks if she wants him to leave, which she doesn't, and they sleep together.
