According to Greta for DVD
Greta's a trip, but she's no vacation. She's sixteen, bright, beautiful, and seriously rebellious, full of sarcastic wit that barely disguises her hurt inside. Pushed aside by her mother, Karen, Greta is shipped off to her grandparents for the summer, and she's not happy about it. In fact, she fully intends to kill herself before the summer is over and is currently compiling a notebook of suicide methods. Acerbic, yet willingly impulsive, Greta is a stunning force of nature, disrupting her grandparents' staid and settled lives and the Jersey Shore community they live in as well. But a near catastrophe gives Greta a wake-up call and demonstrates how deeply her own actions impact those around her. Greta's growing love for her elderly grandparents, along with the excitement of her first summer romance, gradually strips away her defenses, revealing the promising, charismatic young woman underneath her shell.
