The Pagan Lady (1931)

Dot starts out as a bartender in Havana when in walks Dingo Mike (Charles Bickford) and orders up a drink that sounds like something you'd consume on a dare. He drinks the concoction down in one swallow and also manages to outsmart Dot's boss and his rum-running hooligans. You see, Dingo is a bootlegger himself. He literally sweeps the lady off her feet and they set up housekeeping in a tropical hotel full of colorful characters, some of whom are in the bootlegging business too.
