Young teenager Dori Graham (a 13-year-old Tuesday Weld) is popular at school and has landed the dreamy Tommy (Teddy Randazzo) as her boyfriend.
Tommy is a singer and plans on entering an upcoming talent contest being held by DJ Alan Freed.
New girl Gloria (Jacqueline Kerr) arrives on the scene and tries to snag Tommy for herself.
Gloria is rich, though, and plans to purchase a fancy new strapless dress for the upcoming prom to lure Tommy away. Dori determines she must also get such a dress for the whopping sum of $30.
Dori decides she must also get such a dress, but they are a massive $30 and her father (Jack Collins) has cut off her line of credit at the dress shop to teach her to appreciate money.
After a visit to the bank, Dori hits upon a plan to raise money by loaning money to other kids and charging interest.
She ends up loaning the money she has to the villainous Gloria, who takes advantage of Dori’s poor numeracy skills to get her branded a schemer in Tommy’s book.
He ends up breaking off their date to the prom as a result.
Dori has a few tricks up her sleeve to turn the tables on Gloria and win back Tommy.
Dori’s singing voice is provided by Connie Francis.
