Joan Bakewell is joined by a panel of experts to discuss the case of Tanya who is nine years old and seriously ill. Her family don't want her to know what's wrong with her.
As the months go by the medical team become increasingly worried. Tanya's health is deteriorating and she desperately needs medical treatment. But the family disagree - they don't believe medicines will help.
What should the medical team do - can Tanya be given potentially life-saving treatment when her family don't agree? Does Tanya have the right to know what is wrong with her? And as she grows into her teens, to what degree should Tanya decide her treatment?
