The "To-Kon Painters" add color to the lives of people who are short on cash. They're volunteers who will travel anywhere for a good cause, painting buildings and playground equipment free of charge. Most are former social dropouts who once belonged to biker gangs or quit school. We follow them to Lithuania, where they repaint a memorial honoring Chiune Sugihara, a Japanese diplomat who helped 6,000 Jews flee the Holocaust during World War II. The painters must overcome cultural and linguistic challenges to get the job done.

American journalist John Hersey (1914-1993) opened the eyes of much of the world to the aftermath of the atomic bombing of Hiroshima. In this program, Cannon Hersey retraces his grandfather's footsteps and considers the domestic climate in the United States since the start of the Trump presidency. In 1967, amidst racial strife, John Hersey wrote that every white person bore some degree of responsibility for violence against African-Americans. Half a century later, racial and religious prejudices are again spawning attacks. The program explores the seeds of hate and what they might grow into.

Japanese artist Manabu Ikeda makes ultra-detailed drawings with the fine tip of a single pen. As a resident artist at a museum in the U.S. state of Wisconsin, he toiled for 3 years on one large drawing, painstakingly completing a small area measuring only several centimeters square each day. NHK documented his slow, daily progress in the final weeks leading up to the drawing's completion. Ikeda was spurred to make his drawing by the 2011 Great East Japan Earthquake and subsequent tsunami. Starting in a state of psychic pain, he drew nothing but debris at first, but eventually went on to depict a great tree with branches in full bloom. The finished work has elicited a deep emotional response in large numbers of viewers.

In search of wanted criminals, the Japanese police have a secret weapon they use when all other investigative methods fail: miatari finders. In this day and age, when forensic science has become the norm, miatari finders comb the streets relying only on their memory and intuition. Hitoshi Morimoto of the Osaka Prefectural Police is known as the "god of miatari". He has arrested the most number of wanted criminals in Japan. Morimoto uses a unique technique of drawing the suspects into his mind. He talks to photos of the suspects and burns the images into his memory. This program follows Morimoto on his last days before his retirement.

In ancient times, Japan was once covered with trees. Traces of this primordial forest still remain in the deep, untouched woods of Yakushima Island, Japan's first World Heritage Site. A prime example is the Jomon Sugi, a large Japanese cedar that is more than 2,000 years old. However, according to legend, an undiscovered "giant cedar tree" exists on the island. Using cutting-edge technology, NHK began the search for this legendary tree. See what they discover on their quest to find and understand these spectacular cedars.
