Happy Valley actor Sarah Lancashire stars as social worker Miriam who is thrust into the spotlight when a child in her care, Kiri, is abducted and killed after an unsupervised visit to her biological family. The no-nonsense social worker loves and believes in her job, but has a maverick and instinctive approach to dealing with the children she looks after, which draws attention as the media buzz intensifies.
Miriam (Lancashire) and the families at the centre of the storm are forced to ask tough questions, not just of themselves, but of those they love the most.
