 In this reworking of "No, No, Nanette," wealthy heiress Nanette Carter (Doris Day) 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 (Gordon MacRae), 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.
