Hope for Hayley.

Hayley Okines is 8 years old but her body has aged to that of a woman in her 70's due to the rare ageing disease Hutchinson Gilford Progeria. This documentary follows her and her family as they are faced with a potential treatment for the condition. However, the drugs are still only on trial and Hayley's time is running out. A Belgian family with two progeria children are also taking part in the drug trial. The programme ends as Hayley leaves the UK for Boston to begin the trial.
