In his book, Naoki, a funny and charming Japanese boy with autism, gives a unique look into his world. Award-winning director Jerry Rothwell combines the insights that Naoki's book delivers with the lives and experiences of five other people with autism who cannot speak. This cinematographic translation provides an immersion in their special world, an intense sensory place with a lot of beauty. Using a question-and-answer format, the film offers remarkable insights about this specific type of autism. The Reason I Jump shows the journey of a Japanese boy and five others who slowly discover what autism means to them, how it changes their perception of the world and why he behaves the way he does: what is the reason he jumps?
