Actor Danny Dyer sets out to find out whether UFOs are real, prompted by a childhood meeting with astronomer Sir Patrick Moore. He starts in southwest England, walking through crop circles and hearing about cattle mutilations, then sits down with people who describe their own sightings, from unexplained lights to detailed craft, including one man who claims he was abducted. Dyer treats each account with the same mix of curiosity and doubt, pressing for detail rather than taking the stories at face value. The investigation then crosses to the United States, where he visits a UFO research center in Portland, Oregon, and meets researcher James Gilliland to see how serious ufology gathers and weighs its evidence. The film never lands on a verdict; Dyer's own position shifts between skeptic and believer scene to scene, and the witnesses he meets are treated as people with something to explain rather than punchlines. It closes with more open questions than answers about what, if anything, is actually out there.
