The film's ending is like the sign on a hotel room door that says, "DO NOT DISTURB." Or maybe it's like a title card that reads, "SEX IN SESSION."

In either case, the last shot in the film provides a visual clue as to what exactly is going on between the sheets after the fall of that flimsy blanket. It gives us all the information we need without revealing too much—hey, it's 1934, after all. We're barely past Prohibition.
