The Amazon is one of the wildest and least explored parts of the planet. Encompassing 6 countries and 2 million square miles of forest, river and floodplain, it has the highest diversity of life on the planet, but what lies below it is truly shocking. In its deep muddy rivers, clear streams and expansive floodplains a freak-show of fish life has exploded, with some of the strangest shapes and weirdest adaptations on Earth. Hiding in the vast rivers and streams is an electric grid, a bizarre community of fish with a highly sophisticated electric sixth sense. Using electricity, these "Super" fish can communicate wirelessly, control each other remotely and emit shocks that can stop a human heart. This cryptic world has mystified scientists throughout the ages. Now an intrepid scientist, Will Crampton ventures back into the dark jungles where the inspiration for our technology driven world first emerged, in an attempt to unravel their secrets and unlock the electric code.

4-Part documentary series where Lee Min Ho films over a 700-day period in the DMZ to capture nature and animals. Untouched by humans for over half a century, DMZ’s nature would be close to how this land would look when the civilization disappears. Nature and wilderness breathe here freely, and endangered species have made the place their habitat. With the narration of actor Lee Min-ho, the documentary reveals the beauty of Korea’s nature in its rawest and purest form. Here, there is a silent land where humans stepped down. It is a military demarcation line between North and South. It is the foremost front that consumed two-thirds of the 37-month Korean War, and the DMZ, a military operation area that has not been available for more than 60 years since the armistice. It is the largest temperate primeval forest on Earth, where human history of heartbreak and the wild survival of wild animals coexist.
