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

At the head of our gang of embattled prison officer 'screws' is Leigh, a woman who has devoted her entire adult life to this prison and its population. On a wing bursting at the seams, at the front line of a train-wreck of broken bureaucracy and short-term thinking, Leigh keeps her inmates in line and has their backs when they need it. But she is an enigma to her team, and has her own secrets that if discovered could cost her more than her job.

Into the pressure cooker of Long Marsh Prison enters Rose, a 21 year-old trainee officer. It's a baptism of fire even for this street smart young woman. She joins fellow screws Ali, Gary, Don, and Jackie.

Inspired by creator Rob Williams's experience of working and volunteering in prisons, this series brings us a view of incarceration unlike any other. Through a vibrant and multi-layered cast of characters, Screw tackles contemporary stories head on - "but always cut through with comedy, irreverence and heart."
