The Swedish-American radical socialist, songster and poet Joe Hill, became a martyr for the working classes world-wide when he was executed in 1915 for a murder he almost certainly did not commit. His ashes were distributed around the world including New Zealand but no trace of them has ever been found here. Researcher Jared Davidson set out to track them down but in the process uncovered the story of the Industrial Workers of the World (IWW, known as the 'Wobblies') and their repression in New Zealand during the early 1900s and World War 1.
