When Hannah’s sister-in-law, Melissa, manipulates her into paying a hefty grocery bill, Hannah complies but vows to teach her a lesson. Melissa, high-maintenance and entitled, has always relied on others, especially Hannah’s brother, Brandon, to cater to her whims.

Invited to a fancy store, Hannah is trapped into paying $1,470 for Melissa’s groceries. Melissa claims she forgot her wallet, promising to reimburse Hannah. Days later, at a family brunch, Melissa laughs off the debt, calling Hannah greedy and suggesting she consider it a birthday gift.

Hannah decides to take action. She anonymously tips off the dealership about Melissa’s shaky credit, delaying her luxury car purchase. She also warns a bakery about Melissa’s payment habits, prompting them to demand upfront payment for a custom cake.

Melissa’s birthday is a disaster with canceled plans and an almost empty house. Hannah’s final move is a mocking gift card, highlighting Melissa’s entitled behavior. This chain of events forces Melissa to reflect on her life.
