Soon after a young woman breaks off her engagement to a doctor, the doctor is found murdered. Suspicion falls on his ex-fiancé and a pilot with a checkered past.

The growth of small-town juvenile crime starts a movement for the construction of a youth center. The project leaders discuss with town mayor Phineas Wharton Sr. about buying an old warehouse and rebuilding it as the Center. However, Wharton has plans to buy it himself for another project from which he would profit. But the Teen-Agers--Freddie, Dodie, Betty, Lee and Roy--now attending San Juan Junior College, think otherwise.
