German spy thriller about an East-German spy embedded under a NATO general during a war game. 2nd season is about shady financial shenanigans in South Africa during Apartheid, and the main character falling in love with a spy from the West. 3rd season coming soon.
English-language hard Sci-Fi+Spy series. It's an allegory about the East vs. West split, but it's based on a portal being opened to a mirror of our universe, the two sides of which soon diverge and lose trust with each other, thus the spy game. 2 solid seasons.
