A 75-year old man takes care of his 16 year old granddaughter, Dori who has lost her parents. Passive and uninvolved, she believes herself to be plain, inept, and friendless. He is active and loves to swim while Dori accompanies him in a rowboat. However, he is beginning to experience disorientation and lapses of memory. As evidence of senility mounts, Dori must face the possibility of her beloved grandpa's becoming ever more dependent upon her. Instead of his taking care of her, she must be prepared to take care of him. Dori rises to the challenge, getting a new appreciation of herself in the process.
