Upper class Americans Noel and Meg Johnson have a twenty-six year old daughter named Clara Johnson. Clara suffered a head injury as a child which resulted in her being mentally disabled. Clara's mental capacity is equivalent to that of a ten year old. In many social situations, Clara's disability can be passed off as a simple joy of life. The issue of Clara's care has placed a strain between Noel and Meg, the latter who clings to the hope that one day Clara can lead a "normal" life.
