Plot Summary

Tom Rath is a 33-year-old veteran of World War II who lives in Westport, Connecticut, with his wife Betsy and their three children. The Raths reside in a dilapidated house, and despite Tom's steady job at a charitable foundation, the family faces financial difficulties. Tom and Betsy have come to loathe their little house as a symbol of their middle-class purgatory.

Driven by financial pressures and the desire to improve his family's living conditions, Tom learns about a lucrative public relations position at the United Broadcasting Company (UBC) through his friend Bill Hawthorne. Encouraged by Betsy, who dreams of a more comfortable and stable life, Tom decides to pursue the opportunity.

As Tom prepares for his job interview, he continues to experience vivid flashbacks to his experiences during World War II. These flashbacks reveal the profound impact of the war on Tom's psyche, an impact which he hides from everyone. He served as a paratrooper and was involved in intense combat, killing 17 men. One particularly significant memory involves a passionate affair with an Italian woman named Maria, resulting in the birth of a child, a secret that haunts Tom.

After a series of preliminary interviews, Tom's interview with Ralph Hopkins, the senior executive at UBC, goes well and he is offered the job. Hopkins is a powerful and ambitious figure, embodying the corporate ethos of the time. Famous among his coworkers for working harder than anyone else, he often sacrifices his personal life to the demands of his job. He assigns Tom the task of drafting a speech for a national mental health campaign, a project with high visibility and significant expectations. This new role places Tom squarely in the heart of the corporate world, where he confronts the demands and ethical ambiguities of his position.

At the same time, Tom's grandmother dies and he inherits her large house. He sells his old, smaller house and moves into his grandmother's vacated home while planning to divide the large plot into smaller development projects which could make him a lot of money. This is made difficult by his grandmother's butler, who falsely claims that the house was left to him, and by locals who do not want to expand the population of the small, quiet town.

Tom's new job requires long hours and often clashes with his personal values, leading to growing dissatisfaction and tension at home. Betsy becomes frustrated with Tom's absence and the ongoing financial instability, as well as his growing cynicism.

At the same time, Tom meets an old friend, Caesar Gardella, who served alongside him in the war. Gardella witnessed Tom accidentally killing a mutual friend while in combat, a memory that still haunts Tom. Gardella also knew Maria, the woman with whom Tom had his affair. Gardella admits that his family kept contact with Maria but fears that she has gone missing. Tom debates whether he should tell Betsy about his past. The secret of his wartime affair and the existence of his child in Italy weigh heavily on him.

Tom's dissatisfaction with his job and the strain on his family life culminate in a decisive moment. Tom confronts Hopkins, expressing his need to work on projects that align more closely with his principles and to spend more time with his family. Hopkins, recognizing Tom's honesty and integrity, responds positively to his confrontation. He offers Tom a more suitable position that allows for a better balance between work and family.

Gardella passes Tom a letter from Maria, who asks him for financial help. Tom decides to help her, and he shares his secret with Betsy. After an emotional outburst, she accepts Tom's explanation of his struggles to deal with the reality of the war. She agrees to stay with Tom, and Tom sets up a financial scheme to support Maria from America. During this time, a local election allows him to move forward with the development of his grandmother's property, securing his family’s financial future. Tom and Betsy reignite the lost passion in their marriage and celebrate by taking a romantic vacation together.
