Sambizanga

Sambizanga is a straightforward and distressing film about one man being wrongfully imprisoned and atrociously mistreated while imprisoned, and his wife continually trying to find out where he's been taken.

It's presented in a very realistic way which only adds to the tension and discomfort. It's a no-nonsense film with a clear message, and it takes a direct approach in making said message clear. I think what it says is important, and mostly like the approach/execution, though it can lead to some slower parts and a bit of repetition (by design, maybe, but still).

I think this is worth seeking out though. It seems pretty obscure, but I think it received a decent number of votes on the latest Sight and Sound poll, and MUBI has a nicely remastered version of it, so it'll hopefully end up on a few more people's radars in time.
