An Englishman (Leslie Howard) who has been studying painting in Paris for four years, is advised by his art teacher that his work is mediocre and second-rate, and that he lacks promise. So he returns to London, England to take up studies to become a medical doctor, but his older age and introspection make it difficult for him to keep up in his scholastic work. In England, he becomes infatuated - and then obsessed by a blonde, lower-class, slatternly and vulgar, Cockney-accented, illiterate tearoom waitress named Mildred Rogers (Bette Davis)

Snafu annoys his fellow soldiers by listening to loud swing music and banging pots and pans in rhythm. The other soldiers at the barracks are busy studying maps, field manuals, and air recognition charts. Snafu dismisses their interest in studying, and claims he is not going to clunk the enemy over the head with books.
