In 1927 Hollywood, a silent film production company and cast make a difficult transition to sound.

In this reworking of "No, No, Nanette," wealthy heiress Nanette Carter bets her uncle $25,000 that she can say "no" to everything for 48 hours. If she wins, she can invest the money in a Broadway show featuring songs written by her beau, and of course, in which she will star. Trouble is, she doesn't realize her uncle's been wiped out by the Stock Market crash.
