Watch Charlie Cox, Oona Chaplin and Olga Kurylenko in the trailer for Treason

Trained and groomed by MI6, Adam Lawrence’s career seems set. But when the past catches up with him in the form of Kara, a Russian spy with whom he shares a complicated past, he is forced to question everything and everyone in his life. A triangular relationship forms between Kara, Adam and his wife, Maddy; three people who are trying to expose each other’s secrets, navigate political and diplomatic relationships, whilst hanging onto their personal lives, and those they love most.

Created and written by Matt Charman, the five-part limited series stars Charlie Cox, Olga Kurylenko, Oona Chaplin, Ciarán Hinds and Tracy Ifeachor.

Treason launches on Netflix on 26th December.
