A flashback shows how Ellen met George in a naval hospital during World War II while she was dating his friend, Lieutenant Ranney Grahame (Bruce Cowling), a young military doctor whose busy schedule left little time for her. George was a pilot and Ellen swiftly fell in love with him, although the flashback strongly hints he had some capacity for arrogance and selfishness. Nevertheless, they soon married and after the war wound up in a leafy suburban Los Angeles neighborhood.
Unhappily, George is now confined to his bed with heart problems, there is a heat wave and Ellen is spending most her time caring for him. George's doctor is their old friend Ranney, with whom George thinks his wife is having an affair. In response, Ranney suggests George may need psychological help. After Ellen tells her bedridden husband she dreams of having children, he becomes angry. Meanwhile George has written a letter to the district attorney in which he claims his wife and best friend are killing him with overdoses of medicine for his heart.
