Screw, is a six-part prison drama series from STV Studios and Channel 4, by BAFTA nominated writer Rob Williams (The Victim, Killing Eve). Produced by Brian Kaczynski and directed by Tom Vaughan and Jordan Hogg.

This is prison as never seen before - the uncensored, terrifying and often darkly funny reality of life as a prison officer in an all-male prison in 21st century Britain.

At the head of the gang of embattled ‘screws’ is Leigh (Nina Sosanya), a woman who has devoted her adult life to this prison and its troubled population. On a wing bursting at the seams, at the front line of a train-wreck of broken bureaucracy and short-term thinking, Leigh goes above and beyond for her prisoners. But Leigh has her own secrets and a past that if discovered, could cost much more than her job. Will mouthy young Rose (Jamie-Lee O’Donnell), a new recruit with her own agenda, mark the end of the line for Leigh – or prove her unlikely saviour?
