Lady for a Day (1933)

Apple Annie is an indigent woman who has always written to her daughter in Spain that she is a member of New York's high society. With her daughter suddenly en route to America with her new fiance and his father, a member of Spain's aristocracy, Annie must continue her pretense of wealth or the count will not give his blessing. She gets unexpected help from Dave the Dude, a well-known figure in underground circles who considers Annie his good luck charm, and who obtains for her a luxury apartment to entertain the visitors - but this uncharacteristic act of kindness from a man with a disreputable reputation arouses suspicions, leading to complications which further cause things to not always go quite as planned.
