This is a very rare example of a Norwegian Hitchcock-style crime thriller in the same genre as "Rope" and "Dial M for Murder". It is about a lawyer who comes up with a devious plan to kill his half sister and frame another man for the crime. The film features something as unusual as a Norwegian "femme fatale". There is a nerve throughout the movie, and in spite of the film's many weaknesses, it is never boring.

I enjoyed this film immensely, and I was surprised that it is not better known in Norway. The film is basically an American/British style crime thriller set in Oslo. It is not an "intellectual" film, but it is worth watching if you can get it. As far as I know the film has not been released on DVD in 2010. I saw a VHS version.
