According to Greta Trailer (2009)

The trailer for Greta.

Greta’s a trip, but she’s not a vacation. She’s seventeen, bright, beautiful and seriously rebellious, full of sarcastic wit that barely disguises the hurt inside. Pushed aside by her mother, Karen, who is on her third marriage and counting, Greta is shipped off to her grandparents for the summer, and she’s not happy about it. In fact, she tells them that she fully intends to kill herself before the summer is over and is currently compiling a notebook of suicide methods. Acerbic, yet winningly 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.

Hilary Duff, Ellen Burstyn, Evan Ross and Michael Murphy star in Greta, an interracial teen romance now filming in Ocean Grove, New Jersey for Whitewater Films. Duff plays the title role of a waitress who falls for a charismatic, young short-order cook (Ross), only to find out he’s been in and out of a juvenile correctional facility for stealing cars. Now he’s determined to do something with his life, but as their romance heats up, Greta has to overcome the concerns of her grandparents (Burstyn, Murphy) about her new friend’s criminal past.
