In the midst of the Cold War a Norwegian diplomat, Arne Treholt, was convicted of treason against his country for selling secrets to the Soviet Union in the early ’80s. This is true. Not necessarily that he sold secrets as his conviction and twenty year prison term suggests, but just that he was convicted.
In 1992, after serving 8 years of his prison term, Treholt was released and to this day continues to plead his innocence regarding any treasonous activity. This is true.
In 2010, Norwegian filmmaker Thomas Malling made a film depicting the events precisely as they played out back in the 1980s in which Treholt was in fact the leader of a professionally trained black-ops group of ultra-human ninjas. This is true. Not necessarily that Treholt was a ninja mastermind, just that Malling made a film about Treholt being one.
