Keira Knightley trades the Black Pearl for the Black Doves in her new Netflix series, turning from pirate to spy. The new series, now streaming on Netflix, is a thriller centered on Helen, a mother and devoted wife — who just so happens to also be a professional spy who's been passing on secrets about her politician husband to her bosses.

A group of operatives working for private espionage organizations attempt to prevent an international incident around the holidays, in a six-episode drama created by Joe Barton ('Giri/Haji').

When we are first introduced to Helen Webb ( Keira Knightley ), the protagonist of Netflix's newest spy thriller, "Black Doves," she dons a nice dress and perfectly coiled hair that doesn't move an inch.
