"Deep State" centers around Max Easton, an ex-spy whose past comes back to haunt him when he’s summoned away from his new life in the Pyrenees by George White (Alistair Petrie, "The Night Manager", "Rogue One"), head of covert MI6/CIA team, The Section. White convinces Max to return to the field to avenge the death of his estranged son Harry (Joe Dempsie, "Game of Thrones", "Skins"). But the stakes are soon raised when Max finds himself at the heart of a covert intelligence war, immersed in a widespread conspiracy to profit from the spread of chaos in the Middle East. Max enters into a dangerous game as powerful corporations demonstrate that they are willing to go to great lengths to protect their reputation and bury their secrets.
