Elizabeth Halsey (Cameron Diaz) is a foulmouthed, ruthless, and inappropriate teacher. She drinks, gets high, and can’t wait to marry a meal ticket to get out of her bogus day job. When she’s dumped by her fiancé, she sets her sights on a rich, handsome substitute (Justin Timberlake) while shrugging off the advances of the school gym teacher (Jason Segel). The consequences of her wild and outrageous schemes give her students, coworkers, and even herself an education like no other!
