Described as "visceral", "emotional" and "thrilling" by the BBC, the three-part show, penned by Jimmy McGovern, is called Time, and it is set to explore the realities of life in a British jail, through the eyes of two polar opposite men.
Mark Hebden (played by Sean Bean) is the first - a teacher, husband and father, convicted of manslaughter after accidentally killing an innocent man, and facing a four year jail sentence.
Meanwhile Stephen Graham plays Eric Reid, a kind and hardworking prison officer, who is constantly battling against low facilities and staffing to protect his inmates.
Both Mark and Eric are trying to get by in their own bubbles of existence, but things turn sour for Eric after one of the most dangerous inmates in the facility realises his achilles heel, and he's forced to choose between his own principles as a prison guard and his loved ones.
The BBC says what follows is a "story of guilt and forgiveness, punishment and penitence and the impact that prison has on all those who pass through it".
The series is directed by Lewis Arnold, who has previously worked on shows including Broadchuch and Humans, and is expected to begin filming this Autumn.
Sean Bean and Stephen Graham are no strangers to working together, having previously appeared alongside one another in 2012 drama The Accused.
Speaking about his new role, Sean Bean said: "Getting to be involved in a Jimmy McGovern drama again is a real privilege and it will be great to be reunited with Stephen.
"Mark Hebden is another of Jimmy's complex and superbly-written characters and I am looking forward to bringing him to life on screen."
Meanwhile, Stephen Graham added: "It is an absolute honour to be working with Jimmy again, I'm feeling blessed.
"I'm excited to be working with Lewis as I have heard so many incredible things about him as a director, I can't wait to get stuck in. Of course, I am made up to be back on set with Sean."
