Happy Valley star teams up with Keira Knightley for Netflix thriller - and it looks amazing

Keira Knightley is set to star in the upcoming Netflix spy thriller Black Doves - and if the trailer is anything to go by, the show is going to be a major hit. Starring alongside Happy Valley star Sarah Lancashire and Paddington star Ben Whishaw, Keira plays a professional spy who fights to keep her family sage after she is compromised.

The synopsis reads: "Set against the backdrop of London at Christmas, Black Doves is a sharp, action-filled, and heartfelt story of friendship and sacrifice.

"It follows Helen Webb, a quick-witted, down-to-earth, dedicated wife and mother — and professional spy. For 10 years, she’s been passing on her politician husband’s secrets to the shadowy organisation she works for: the Black Doves. When her secret lover Jason is assassinated, her spymaster, the enigmatic Reed, calls in Helen’s old friend Sam to keep her safe.

"Together, Helen and Sam set off on a mission to investigate who killed Jason and why, leading them to uncover a vast, interconnected conspiracy linking the murky London underworld to a looming geopolitical crisis."

Featuring new music from Raye, who has covered Bang Bang (My Baby Shot Me Down) for the project, the show is set to land on Netflix from 5 December - and viewers already can't wait. Taking to YouTube to discuss the trailer, one person wrote: "Guess I'll have to keep Netflix for a little longer," while another person added: "Keira and Ben are going all john wick in here. I never thought I will see that day. This I got to see." A third person wrote: "Finally the queen of period dramas in a modern day story as a spy."
