Georgina (Lynn Redgrave) is a carefree and childlike 22-year-old who finds more joy in her relationships with children than with the adults in her life. Her parents' employer, James Leamington (James Mason), proposes marriage, but Georgy avoids giving him an answer, as the idea of romance confuses her. When Georgy finds herself the caretaker of a baby girl, she seeks to find a way to shoulder the new responsibility while maintaining her childlike innocence.
