The film stars as Elizabeth Halsey, a gold-digging, foul-mouthed middle school teacher who hates her job, her students, and her coworkers. After being dumped by her wealthy fiancé, Elizabeth is forced to return to the classroom. Her new goal? To raise enough money for breast augmentation surgery, believing it’s the key to snagging a new rich husband.

Delivering one of her most fearless comedic performances, Diaz leans into Elizabeth's flaws without ever asking for the audience's pity.

However, her plans are foiled when she learns that the ticket is actually worth nothing, as it's an old ticket that has expired. To make matters worse, she meets Scott Delacorte (Justin Timberlake), a substitute teacher who is the complete opposite of Elizabeth - he's charming, caring, and wants to make a difference in the lives of his students.
