She is in love with an ambitious singer Tommy Rogers, but she rejects his offer to enter a talent contest sponsored by Alan Freed.

However, when she sees a new student Gloria Barker who arrives and announces that she will be wearing a strapless evening gown in blue, Dori becomes disappointed.

When she and Arabella are watching Freed's television show featuring upcoming rock and roll performers that night, Dori is worried that Tommy is attracted by Gloria, especially his newfound fame shortly after he has won the talent contest.

Dori attempts to buy a strapless evening dress at Miss Silky's shop, but realizes that the charge account has been already closed.

Dori then decides to become a banker and borrows fifteen dollars from Arabella for a primary deposit after asking Mr. Bimble for a loan and providing collateral as a requirement–based on the principles of banking.

Dori asks her father's advice about loans in a coyly manner, and he suggests that bankers can foreclose and take ownership of collateral.

After several performances by various rock and roll artists, Dori and Tommy reconcile and reunite on the dance floor after the latter's apology.
