Bafta-winning writer Jack Thorne is back with another dark drama that deals with challenging and poignant subject matter.
Last year he won his accolade for National Treasure, a series about historic sex abuse, and now he returns with Kiri, a story about transracial adoption.
We follow Miriam, an experienced social worker who is caught up in a police investigation when Kiri, a nine-year-old girl, goes missing on a supervised visit.
Meet the cast, led by Sarah Lancashire, below…
