The Bachelor is Dick Nugent (Cary Grant), a sophisticated and debonair artist - no wonder Bobby-Soxer Susan Turner (Shirley Temple) develops such a crush on him. It doesn't matter to her that she's just seventeen and he's in his forties... When Susan is found in Dick studio after hours, he's hauled before the judge - who just happens to be Susan's older sister Margaret (Myrna Loy). Although convinced that Dick is blameless, Margaret devises an inventive punishment - he has to take Susan out on 'dates' until her infatuation fades. But how long will that take...?
