Dick Powell and Ruby Keeler play two young hopefuls struggling to make it on Broadway. Even falling in love has its hardships, as Powell's high-brow Eastern family is determined to break them (and the show) up. More complications set in when his brother falls for Keeler's wise-cracking roommate.

Onstage, the itinerary of a Junior Stargazer/Space Cadet convention is spectacularly disrupted by world-changing events while each attendee and their family members deal with their own interpersonal issues.
