Girls Town (1959)

Chip is killed accidentally while trying to rape a blonde girl, who runs. Silver becomes the number one suspect even though she has an alibi, but due to previous brushes with the law she's sent to Girls Town, a home for young women in trouble with the law which is run by nuns. Silver is rebellious and causes trouble at the school, and her friend Sarafina totters near the brink of self-destruction because of an infatuation with a young singer. Meanwhile Chip's father hires a detective to find out the truth, and Chip's friend Fred gets Silver's sister in trouble at a drag race. Silver has a lot of problems all right.
