Rod Roddenberry was seventeen when his father Gene Roddenberry died, and for years he kept his distance from the franchise that made the family name famous. This film follows him as he sets out to understand the man behind Star Trek, visiting fan conventions, production offices, and archives, and sitting down with people who worked alongside his father, including cast members and writers from the original series and its spinoffs. Interviews trace how a former Los Angeles police officer turned television writer built a show that pushed for a multiracial bridge crew and stories about tolerance during the 1960s, and how that vision grew into conventions, spinoff series, and a devoted global fan base. Rod's search is personal rather than promotional: he asks people who knew Gene well what kind of father and man he actually was, not just what kind of creator. The film moves between behind-the-scenes footage, present-day interviews, and Rod's own narration as he pieces together a portrait of a parent he barely got to know.
