TV tonight Who Do You Think You Are? — Proud: Ruth Jones looks into her past

Ruth Jones never met her paternal grandfather Henry Richard Jones, who died before she was born, but her desire to learn more about him is so heartfelt that we feel just as invested as she does. The Gavin & Stacey star is thrilled to find out that Henry was a dispenser who was involved with the Medical Aid Societies in South Wales and her pride is palpable as she reads his letters to the Government, including Health Minister Aneurin Bevan, urging it to let the societies take part in shaping the development of the NHS.

Therapist Grace Fraser is married to charming oncologist Jonathan, with son Henry thriving at an elite New York school. All in all she’s living her best life.

A Quiet Place, 9pm, Film4

TV tonight A Quiet Place — John Krasinski stars

A supremely terrifying movie directed and co-written by its star John Krasinski. The setting is a post apocalyptic near future in which two parents (Krasinski and his real-life wife Emily Blunt) and their kids struggle to stay alive in a world that has been overrun by sightless monsters – all ears and teeth – that hunt by sound. The tension is wound ever tighter until we’re ready to scream, even if the characters can’t
