"Dave the Dude", a very successful New York City gangster, has one superstition: he believes that the apples he buys from alcoholic street peddler Apple Annie bring him luck. Annie assures the Dude that his latest purchase is especially lucky. He then meets Elizabeth "Queenie" Martin, the daughter of a friend and speakeasy owner recently murdered for owing a lot of money to the wrong people. Queenie offers to pay him $5 a week from her cashier's salary toward the $20,000 owed him. Instead, trusting Annie's claim, he decides to make Queenie a nightclub star. To the astonishment of his right-hand man, "Joy Boy", he succeeds, and Queenie is able to pay off all her father's creditors after two years, just as Prohibition ends.
