Reincarnation claims get the science treatment here: people who say they remember dying in past lives, and researchers trying to work out whether any of it can be tested. The film follows therapists who use hypnosis and regression sessions to draw out these memories, including clients who describe reliving violent deaths from another lifetime. Scientists then pick apart the accounts, checking names, dates, and details against historical record and asking what else, memory distortion, suggestion, cultural expectation, could produce the same vivid sense of a former self. No side gets the last word; the film lays out the therapy sessions and the skeptical rebuttals side by side and leaves the viewer to weigh them. It stays close to individual cases rather than grand theory, which keeps the claims concrete even when the evidence for them stays thin.
