The series one finale saw tragedy strike C Wing at Long Marsh male prison, which leaves Leigh Henry (Nina Sosanya) and her beleaguered staff looking to make a fresh start.

But with changes at the very top and a fresh intake of both staff and prisoners, Leigh’s new bond with Rose (Jamie-Lee O’Donnell) will be tested to the limit.

The guards continue striving to improve the complex lives of those in their care, only for rumours of an undercover cop on the wing to upend the order and threaten to blow open a criminal plot involving at least one of the officers.

Caroline Hollick, Head of Channel 4 Drama, says: “We’re thrilled to welcome back the staff and prisoners of C Wing.

“Rob has created an iconic Channel 4 prison series with a fantastic cast and we can’t wait to jump back into the drama, humanity and humour of life behind bars in series two.”

Screw series two will be filmed in the Kelvin Hall in Glasgow.
