After the body of a young woman is recovered from Lake Mattsee, the two cops not only face a major professional challenge that takes them into the dark past, but also come into contact with Mattsee's dark history and reach their limits privately.
Unfortunately the movie Dunkle Wasser is not yet available on HBO Max.
