The book "The Reason I Jump" introduced readers around the world, for the first time, to the true emotions of a person with autism. Author Naoki Higashida is severely autistic, but can "talk" with the help of an alphabet board or a computer. 2 years after he was profiled in the NHK Documentary What You Taught Me About My Son (2014), the director, who is now suffering from cancer, re-visits Naoki, asking him a crucial question: "How can people who are suffering find happiness?" It's a remarkable story about life from the words of a young autistic author.
