If you loved Halbblut, try Enigma - Das Geheimnis
Eine Brücke zwischen einem Film, den du schon gesehen hast, und einem, den kaum jemand kennt. Das teilen sie, und was der zweite macht, was der erste nicht macht.
Was sie teilen
Both films are directed by Michael Apted, and they both carry the paranoid mood tag, and they sit in Mystery / Thriller territory. If that's the register that drew you to Halbblut, the second film will land in a comparable space — through a different lens.

What Enigma - Das Geheimnis is
Bletchley Park, 1943. Snowfall. A drowned body in the lake. Young codebreakers race to crack a revised Naval Enigma before U-boats sink Allied convoys, even as one of them suspects a mole. Apted's procedural simmers nicely.
