Synopsis: San Francisco's Barbary Coast is the place to be at the turn of the century and it's where aspiring businessman and piano-playing Johnny Cornell and his troupe entertain the well-to-do and those who have remained after the gold rush. The quartet includes the soulful, singing Trudy Evans, always cheery Dan Daley and his partner Beulah Clancy. When the quartet is fired from a job for being too entertaining, Johnny decides to open his own dance hall. Soon they are mixing with the elite Nob Hill socialites and Johnny falls for and marries Bernice Croft an heiress whose intentions are purely selfish. Johnny opens an opera house that quickly drains his fortune and sends Bernice packing.
