Based on the best-selling book by Naoki Higashida, The Reason I Jump is an immersive cinematic exploration of neurodiversity through the experiences of nonspeaking autistic people from around the world. The film blends Higashida's revelatory insights into autism, written when he was just 13, with intimate portraits of five remarkable young people. It opens a window into a sensory universe that guides audiences to Naoki’s core message: not being able to speak does not mean there is nothing to say.
