Filming has been completed on BBC One's Rules of the Game, "a gripping four-part thriller about sexual politics in the modern workplace".
Due on screens next year, Rules of the Game stars Maxine Peake alongside Alison Steadman, Rakhee Thakrar and Susan Wokoma.
Releasing new photos, the BBC said Silk star Peake plays Sam, "a hard-headed manager at a family-run business" in the northwest of England.
"However, when Sam arrives at work one day to find a dead body in the office reception she is forced to reckon with not only murky behaviour in the present, but murderous secrets from the past as well," the broadcaster continued.
"Rakhee Thakrar (Sex Education) plays Maya, a new HR Director who tries to shake up the old-fashioned lad culture, and begins investigating historic cases of misconduct.
"Alison Steadman (Gavin & Stacey) plays Anita, a member of the board and the cold, hardened widow of narcissistic company founder Harry.
"Susan Wokoma (Enola Holmes) plays DI Eve Preston, an immensely driven, thick-skinned, no-nonsense detective who is investigating a case centred around the company."
"What a glorious cast," said Peake. "Working alongside my fellow sisters each day, with their commitment and understanding towards Ruth Fowler's script about sexual politics in the workplace, with Jennifer Sheridan directing, has reminded me once again why we need to keep fighting for more women to have a voice in the filmmaking process."
