An intimate portrait of three children who suffer from a rare disorder called Progeria - a Greek word meaning 'advanced ageing'. A disorder that puts their bodies, but not their minds or spirits, into fast forward. The children, who have an average life span of 13 years, talk openly about their hopes and fears and how they cope with day-to-day life. The story covers both the scientific and emotional stories, and calls upon experts to explain the condition and the treatments available.
