Charlie Cox, Ciarán Hinds, Oona Chaplin and Olga Kurylenko star in this high-octane thriller from 'Bridge of Spies' writer.

We all know what it's like after the feeding on Christmas Day and that weird in-between period before New Year's Eve when you're only thoughts are: What day of the week is it? When is the more acceptable time to crack open another bottle of Baileys - 10am or 12pm? And most importantly, what is there to watch on the telly? Judging from the trailer, 'Treason' could be a good shout for your Netflix viewing.

The five-part series comes from writer, showrunner and executive producer Matt Charman, whose Tom Hanks thriller 'Bridge of Spies' was nominated for a Best Original Screenplay Oscar in 2015.

Charlie Cox stars as Adam Lawrence, who has been bumped to the Chief of MI6 following an attempted murder on former Cheif, Martin Angelis (played by Ciarán Hinds). This sudden promotion comes at the same time as the reappearance of Kara ('Quantum of Solace' star Olga Kurylenko), a Russian spy who Adam shares a mysterious past with.

Check out the thrilling trailer of the series below.

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.

'Treason' begins on Netflix on St. Stephen's Day, December 26.
