LONDON — The BBC has commissioned “Luther” creator Neil Cross to write “Hard Sun,” a pre-apocalyptic crime drama set in contemporary London.

The six-part series centers on detectives Elaine Renko and Robert Hicks, partners and enemies, who seek to enforce the law and protect their loved ones in a world that every day slips closer to certain destruction.

The series is the first commission for the rebooted Euston Films, which is headed by Kate Harwood, the former head of drama production for England at the BBC. Euston Films is part of FremantleMedia, and the show will be sold internationally through FremantleMedia’s global distribution arm, FremantleMedia International. The executive producers on the series are Harwood for Euston Films and Elizabeth Kilgarriff for BBC One. It will film in and around London, and casting will be announced in due course.

Cross said: “Imagine the world you see when you look out your window… except it’s been given a death sentence. This isn’t science fiction. This is the real world. There’s no hero to come save us; no contingency plan. We’ve got five years. This is the world of ‘Hard Sun’… and the world of Elaine Renko and Robert Hicks. What’s it like, trying to keep order, trying to enforce the law in a city that, day by day, slips closer to certain destruction?”

Polly Hill, controller of BBC drama commissioning, said: “Neil has written a crime series that is bold, ambitious, relevant and dark but it’s also very moving and told through complex extraordinary characters. It’s brilliantly written and very exciting.”

Harwood, managing director of Euston Films, added: “We are delighted and proud that the first commission for a rebooted Euston Films is a Neil Cross project of such scale and nerve. The concept of ‘Hard Sun’ is characteristically bold, richly peopled and of course deliciously scary. We can’t wait to get started.”
