With Sofia Helin, Rafael Pettersson, Dag Malmberg, Sarah Boberg. When a body is found on the bridge between Denmark and Sweden, right on the border, Danish inspector Martin Rohde and Swedish Saga Norén have to share jurisdiction and work together to find the killer.
The Bridge. 2011. A Swedish and Danish crime drama co-production. I've watched the first season on Netflix with subtitles. It was about catching a serial killer, and it was absolutely fantastic. (Remade as a British/French series "The Tunnel", and as a U.S./Mexican series "The Bridge".)
