When his destituite widowed sister-in-law—whom he had never stopped harbouring feelings for—and her ne'er-do-well son come to live with him after World War II, a mentally-ill farmer who spends all his time destroying unexploded ordnance scattered across the countryside finds a new purpose in his lonely life.

While working on a novel in his country home in Connecticut, married writer Tony Barrett (Cooper) becomes attracted to Manya (Sten), the daughter of a neighboring farmer. Manya is unhappily engaged to Frederik (Bellamy). Due to a snowstorm, Tony and Manya are trapped together in his house overnight. The next day, Manya's father insists her wedding to Frederik take place in spite of Manya's misgivings. Drunkenness and jealousy result in tragedy at the wedding reception that night.
