Playboy Number One 1937

Professor Pierre Ginsberg, extraordinary French instructor, is sailing with a wealthy couple as their instructor and guide in France. But when his client tries out his French in the dining room and everything is wrong, he fires Ginsberg. Two gangster-type Americans ask Ginsbeg to order them a meal, and advise him to get a girl for the ship's ball that night. Ginsberg, of course, picks the wife of one of them.
