The Little Giant

When Prohibition ends, a beer baron sees the writing on the wall, quits the rackets, and tries to break into California society.
Prohibition is ending so bootlegger Bugs Ahearn decides to crack California society. He leases a house from down-on-her-luck Ruth and hires her as social secretary. He rescues Polly Cass from a horsefall and goes home to meet her dad who sells him some phony stock certificates. When he learns about this he sends to Chicago for mob help.
