A Discovery of Witches is a TV adaptation of the All Souls Trilogy by Deborah Harkness. It follows the story of Diana Bishop, an alchemical history professor at The University of Oxford who, after accidentally calling an elusive, long-thought-lost manuscript, is compelled to embrace the magic in her blood she has sought to keep out of her life and engage in a forbidden romance with charming vampire Matthew Clairmont.

A thrilling story about blood, love and human relationships set in the steel town of Port Talbot. Loner Sam (Jacob Ifan, Cuffs) has his life transformed when he comes into possession of a gun and starts to break the law. His ambitious policewoman sister Gina (Catrin Stewart, Doctor Who, Stella) is paid to uphold it and makes it her mission to find the owner of the weapon. The family saga plays out against an inquiry into the shooting of a local businessman that raises questions for Sam. This series is firmly rooted in its location in Port Talbot and the Afan Valley, and Bang breaks new ground for S4C where the purposeful use of English dialogue is used to reflect aspects of this community.

Cuffs is a fresh, authentic and visceral drama that will take the audience on an exhilarating ride through the challenges of front-line policing. Adrenalized and vibrant, the show is packed full of dramatic incidents and colourful characters. From a booby trapped cannabis farm in a suburban semi to an elderly farmer's wife with a shotgun, the stories are surprising and exciting. There will be more absurd altercations - such as a middle-class dog-napping or fisticuffs between pensioners - as well as the daily grind of speeding drivers, city-centre shoplifters and Saturday night drinkers.
