's character Greta is just plain dramatic.
How else do you describe a teen who kicks off a summer visit to her grandparents' with "I want to kill myself"? Still, there's a few things she plans to do first – including getting a tattoo.
The movie, Greta
, is ultimately a teen romance with Duff, 21, starring as rebellious 17-year-old Greta, who finds love with a young ex-convict while she's spending the summer with her grandparents on the Jersey shore.
Ellen Burstyn and Michael Murphy costar as the lucky grams and gramps, and Evan Ross, 20 (and the son of Supreme singer Diana Ross), plays her love interest, Julie.
