High school student Olive Penderghast (Emma Stone) finds herself the victim of her school’s ``rumor mill`` when she lies to her best friend Rhiannon (Alyson Michalka) about a weekend tryst with a fictional college freshman. Word quickly spreads of Olive’s promiscuity and, much to her surprise, she welcomes the attention. When she agrees to help out a bullied friend by pretending to sleep with him, her image rapidly degrades to a more lascivious state and her world begins to spin out of control. As she helps more and more of her classmates and her lies continue to escalate, Olive must find a way to save face before the school’s religious fanatic Marianne (Amanda Bynes) gets her expelled and she loses a shot at attaining her own happiness.
