New Zealand filmmaker David Farrier redefines the meaning of "tourism" and points the camera to a lesser-known but increasingly prevalent field - dark tourism.From nuclear disaster sightseeing in Japan, to Colombia's travel craze with drug lord Pablo Escobar as the theme, to wilderness adventures in the Turkmenistan border area, Farrell sets out on destinations full of historical shadows and mystery.Not only did he visit these gloomy and alternative attractions, he also met travelers attracted to them, and those who told these stories day after day.During this journey, death, violence and history intertwined into a disturbing yet irresistible attraction that makes people wonder: Why are we attracted to these dark places?
