Kleo is an eight-part Netflix series that is set after the fall of the Berlin Wall and follows the titular former spy killer named Kleo Straub.
We see her after she is set free and embarks on a revenge spree against those who conspired to betray her. Kleo had been imprisoned despite successfully performing a crucial task for her nation, so naturally, she's not too pleased about this!
Kleo is set in the late 1980s and early 1990s, and the thrilling German-language series was created by Hanno Hackfort, Bob Konrad, and Richard Kropf. There's a great cast attached too, which we're going to take a look at.
As well as the aforementioned Kleo Straub, there's a whole host of other characters to get to know.
