Mohamed Nasheed had already been ousted as president of the Maldives by the time Jon Shenk completed this documentary. However, it retains its potency as a portrait of the democratically elected leader and crusading environmentalist, who sought to alert the world to the very real prospect that the 1,200 islands comprising his Indian Ocean paradise could be submerged by the rising tides of global warming. Shenk draws on archive material to chronicle Nasheed's courageous battle against longtime dictator Maumoon Abdul Gayoom, but it's the unprecedented access he has to his subject that makes this movie so revealing and compelling. Holding cabinet meetings underwater and delivering grandstanding speeches to the United Nations and the British parliament, Nasheed is clearly a master self-publicist. But he is also tirelessly committed to his cause, which makes his patronising treatment by the industrial powers at the 2009 Climate Change Conference in Copenhagen deeply dismaying.
