Indigo Children are, by their own account, astral beings born with indigo-colored auras and given psychic and healing gifts to guide humanity toward a higher purpose. Journalist Gavin Haynes travels from England into this small American community to find out who believes this and why. He gets his aura photographed and his past lives read by a movement leader, sits through a holistic dentistry exam performed by a mother-daughter pair of practitioners, and attends a concert by The Underachievers, a rap duo preaching Indigoism as a lifestyle. The subjects come across as sincere and self-assured, and Haynes treats them with more curiosity than mockery. Set against their testimony is the clinical view: a psychologist interviewed in the film argues that what looks like a spiritual gift is often undiagnosed ADHD, and that families encouraging the Indigo identity may be steering children away from treatment they need. The film sits in that gap between the two accounts without resolving it, tracking a movement that began in the 1970s and the medical skepticism that has followed it since.
