New BBC One drama Better starts filming in Leeds this week, produced by newly-launched Northern Sister.

The 6 x 60 series is from the writers of Humans, Sam Vincent and Jonathan Brackley and is a redemption story set in Leeds, using the landscape of the city and surrounding countryside as a backdrop.

After a family tragedy is narrowly averted, a corrupt police detective undergoes a painful moral awakening and decides to put right 20 years of wrongdoing – but satisfying her newfound conscience will be complicated.

She slowly realises that her redemption will only be complete once she brings down the powerful gangster she has worked for all this time, a man she helped rise to power, and has come to love like a brother.

Better is executive produced by Mona Qureshi for the BBC and Jane Featherstone, Chris Fry, Lucy Dyke, Vincent and Brackley for Sister in association with Northern Sister.

The writers said at the time of the commissioning announcement: “Better asks if a truly bad person can ever become good, and if so, how that could happen. The idea has been in our heads for 10 years, and we”re hugely fortunate to be telling it at last with the help of our old friends at the mighty Sister, in the great city of Leeds – and for BBC One, the perfect home for this very British story.”

London-based Sister launched its northern office last year, headed by The Split executive producer Lucy Dyke. Northern Sister is based in Manchester and has a remit to nurture relationships with creatives across the north.
