She doesn't give an "F."

Some teachers just don't give an F. For example, there's Elizabeth (Cameron Diaz, The Green Hornet). She's foul-mouthed, ruthless and inappropriate. She drinks, she gets high, and she can't wait to marry her meal ticket and get out of her bogus day job. When she's dumped by her fiancé, she sets her plan in motion to win over a rich, handsome substitute (Justin Timberlake, The Social Network)—competing for his affections with an overly energetic colleague, Amy (Lucy Punch).

Then, when Elizabeth also finds herself fighting off the advances of a sarcastic, irreverent gym teacher (Jason Segel, Forgetting Sarah Marshall, TV's How I Met Your Mother), the consequences of her wild and outrageous schemes give her students, her coworkers, and even herself an education like no other.

Critics and audiences alike give it an "A," and so will you. Learning was never so funny, especially in this Unrated Edition!
