Just after World War II, retired philosophy professor Henry Barnes Edmund Gwenn confides in his friend, law professor Edward Bell Gene Lockhart that he plans to commit suicide. He speaks with calm logic, convinced that retirement has rendered him useless and that he should not linger and consume the world’s scarce resources. It’s later revealed that Henry’s wife has died and his son was lost in the war, facts that deepen the sense of purposelessness he wrestles with. Edward, refusing to let him fall into despair, reaches out to Dr. Philip Conway Griff Barnett, who examines Henry and finds him in unexpectedly good health. Henry asks for sleeping pills, but Conway limits the doses to two at a time to prevent a lethal overdose.
Jason Taylor William Holden is a United States Navy veteran who survived the sinking of the USS Vincennes and is now a GI Bill student, aiming to become a chemistry teacher. He and his young, pregnant wife Peggy Jeanne Crain are living in a cramped camper while Peggy hunts for a better apartment, so Jason can study without constant anxiety. The postwar housing crunch has left many veterans juggling marriage, children, and crowded living conditions, with Edward’s VA housing office overwhelmed by requests.
On a campus bench, Peggy sparks Henry’s interest with her frank, energetic slang and her vivid zest for life. She fills him in on Jason and their housing crisis, and she warns him about the unresponsive “creep” housing administrator, Edward—though she soon discovers that Henry is good friends with Edward. When Peggy presses the issue, Edward assigns her and Jason to live with Henry, hoping the arrangement will relieve the pressure and bring some stability to all of them.
The sudden presence of a young, bustling couple disrupts Henry’s quiet routine, at first aggravating him. Yet the household gradually grows into an improvised, makeshift family. Jason and Peggy pitch in with chores, and Peggy even starts calling Henry “Pop.” Henry also begins teaching a free class for the wives of GI Bill students, empowering them to keep pace with their educated husbands and easing some of the fear of being left behind. Yet Henry remains haunted by the date March 1, the day he had intended to end his life.
Meanwhile, Jason’s college path buckles under financial strain. He contemplates dropping out to take a job selling used cars in Chicago, a decision that would upend Peggy’s hopes and their plans for a stable future. Peggy’s mood worsens, and she experiences a miscarriage, a devastating blow for the fragile little family. After the miscarriage, Henry reveals that his intention to kill himself had not yet vanished, but Peggy’s pain and Jason’s struggles begin to move him toward a different choice.
Jason ultimately quits school and moves to Chicago, leaving Peggy to recover at Henry’s home. Henry tries to help by encouraging Jason to return, even as the young man secretly re-enrolls and aims to pass his exams. He faces his toughest barrier in chemistry, but with encouragement from a Navy veteran professor, he keeps going and ultimately succeeds in most of his tests, proving to himself—and to Henry—that perseverance can rewrite a life chart that had seemed fixed.
The arc turns when Henry, who had again set the date to end his life, has a shift of heart. He takes his saved pills, only to be met by Peggy and Jason, who brew coffee and help him walk through the worst of the effects. In that moment, Jason reminds Henry that countless men who fought and died in the war would have given anything to have the chance to continue living. The support of his two young friends, along with his circle of professor colleagues, helps Henry rediscover purpose and companionship.
In the end, the household remains a source of mutual care and renewal. Henry is joyfully reunited with Jason, Peggy, and their circle of academic friends, and Peggy—radiant with hope—announces that she and Jason plan to welcome another baby. The film closes on a note of quiet optimism, underscoring how the postwar era’s challenges could be faced not as solitary struggles but as shared, communal resilience.
