Documentary about 12-year-old Melissa and 14-year-old Ryan as they look after their single mum, who suffers from mental and physical illnesses. For the past five years they've taken on the household responsibilities and are just two of the 175,000 young carers in Britain today. The film looks at how they are coping with their mum's increasing ill-health and asks whether, without any outside help, they'll ever be able to leave her and lead independent lives.
