A pangolin is hunted every five minutes in the world on average; it’s the most seriously poached mammal on earth. The film crew followed Dr. Ching-Min Sun in his tracking for pangolins. They monitored their life journeys and tried to dig out burrows and the truth behind their deaths. In 50 years, Taiwan has transformed from a hunting ground to a breeding ground for pangolins. After years of conservation, pangolins in Taiwan are increasing with one of the highest wildlife densities in the world.
