Cooper and Fry — Season 1

DC Ben Cooper, a local officer with deep roots in the Peak District, is paired with newcomer DC Diane Fry as they investigate crimes around the fictional town of Edendale. Robert James-Collier and Mandip Gill star.

Showtrial — Season 2

When a prominent climate activist is left for dead in a hit-and-run, his dying accusation points to a police officer with a reason to want him silenced, and the five-part season follows the case from investigation through the courtroom. Showtrial is an anthology, so there's no need to have seen Season 1 first.

A modern-day reimagining of Christie's crime-solving duo, timed to premiere on the writer's own birthday. Antonia Thomas and Josh Dylan lead, with Imelda Staunton among the cast.

Time — Season 3

David Tennant joins Siobhan Finneran for the third season of the acclaimed prison drama. Set inside a young offenders institution, the new story follows prison chaplain Marie-Louise as she struggles with a crisis of faith and clashes with veteran officer Bailey following a tragedy inside the institution. BritBox has announced the season as coming soon in North America; a U.S. premiere date has not yet been announced.
