Alison Hammond presents the show giving people the chance to perform the one song that tells their story - often in front of a crowd for the very first time. Mentors Paloma Faith and Sam Ryder watch and listen to the performances. In the first episode, Alison heads to Liverpool, where a teenager sings Bocelli for the foster mum he can't find words to thank, and a kidney transplant recipient brings Sam and Paloma sprinting out into the downpour. With only one place available at the grand final at London's Hackney Empire, Sam and Paloma face an impossible choice.
