Ross Kemp looks at the issue of homelessness by sleeping out on the coldest night of the year in Cardiff with some rough sleepers. He also meets families torn apart by homelessness.
It's thought that 1 in 20 children in Britain care for sick relatives. Ross meets a 15-year-old who looks after her schizophrenic mother and an even younger boy who cares for his sister, who has cerebral palsy and visual impairment.
Ross meets teenagers who say they carry knives for self protection, parents who fear for their children's lives and community leaders taking drastic measures to put an end to the violence.
Ross meets some of Britain's problem online gamblers, including some who have to go off-grid to escape their addictions. He also visits the parents of two young men who took their own lives after racking up serious debts.
