Keira Knightley's Helen has a complicated relationship with her assassin friend Sam, who has an unbelievable first target in Black Doves season 1.

We already know that Maggie's connection to Kai-Ming is as a childhood friend, and Phillip was a reporter who had published multiple articles about her life, but Jason's link is only revealed during a later conversation between Helen and her duplicitous handler Reed ( Sarah Lancashire ).

In the season 1 finale of the spy thriller, secret identities begin to crumble under the weight of relationships.

Whether you’re a fan of high-octane action or stylish thrillers, this series is a gift worth unwrapping this festive season.
