A widow named Mrs. Marsan lives in an apartment complex and pries into her neighbors' personal affairs. She is happiest when unsuspecting lovers argue and she can focus her opera glasses on them. Her innocently disingenuous nosiness helps to bring about a marriage between two cripples, a therapeutic romance for a depressed war widow, a happy ending in a sordid triangle affair. Even her death from heart trouble helps a friend, radical and fanatic, somehow learns a lesson in elementary humanity.
