New York manicurist Mamie Murphy plans to marry a rich man, so she repeatedly turns down the proposals of honest reporter David Haines. When she is announced the winner of $2,500 and a ticket worth $150,000 for champion horse Lady Luck, if the horse wins an upcoming race, Mamie is pursued by wealthy sportsman Jack Conroy and nightclub owner and racketeer Tony Morelli.
