The four-person theatrical troupe is working at the hotel because they went to the expensive restaurant in the hotel and had no money to pay the bill! They were forced to work in the kitchen. Nancy Walker is the only one who works as a maid, discovering Dick Carson in his suite and does an impromptu audition for him. He throws her out. They finally get to do a number for Carson and he falls in love with Candy. The whole point of the title is that Candy is totally superstitious and finds bad things all the time, hence she calls herself Lucky Me.
