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 (Keira Knightley), 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 (Andrew Koji) is assassinated, her spymaster, the enigmatic Reed (Sarah Lancashire), calls in Helen’s old friend Sam (Ben Whishaw) 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.
