It's believed that as many as 800,000 people under the age of 18 care for sick parents or siblings: one in 20 children in Britain. In the second episode of his new series, Ross Kemp investigates the hidden crisis of young carers and starts in Blackburn where he stays the night with the Haywood family. Lizzie, 15, carries out care work for her mother, Donna, who suffers from serious physical difficulties and schizophrenia. Ross discovers that due to her care workload, Lizzie often does her homework late into the night. Accompanying a charity worker, Ross is shocked when he meets young carers as young as five. They include Ali, who cares for his his sister Zainab, a cerebral palsy sufferer with epilepsy and visual impairment. Their mother, Hanifa, says she would be lost without Ali's help. Ross discovers how much money young carers are saving the economy but at the same time, funding for services to help them is falling. And in Manchester, Ross attends a powerful play written and performed by young carers.
