When a high-ranking MI6 officer’s dark past suddenly comes back to destroy everything he’s built, the line between loyalty and betrayal becomes dangerously thin.

Treason follows Adam Lawrence (Charlie Cox), one of Britain’s top spies, whose seemingly perfect life is shattered when a Russian operative (Olga Kurylenko) threatens to expose secrets from his past. As old alliances crumble and new enemies emerge, Adam must race against time to protect his family and his country — even if it means betraying the people closest to him.

Packed with intense political intrigue, shocking twists, and moral dilemmas, this five-episode limited series delivers the perfect mix of espionage, suspense, and high-stakes drama. With strong performances from Charlie Cox, Olga Kurylenko, and Oona Chaplin, Treason keeps you guessing until the very last minute.

If you love sophisticated spy thrillers like The Night Agent, Bodyguard, or The Bourne Identity, this is a must-watch on Netflix.
