Star Trek: Insurrection

Something is afoot in Federation space. The android Lieutenant Data (Brent Spiner) has apparently malfunctioned, and is disobeying orders from his superiors, revealing the existence of a hidden base to the apparently primitive natives of a planet he is temporarily stationed on. When Captain Picard (Patrick Stewart) and Worf (Michael Dorn) follow him, they discover a planet with a much bigger secret... a fountain of youth. Unfortunately, hostile elements are attempting to move the natives from this paradise, and certain Federation officials seem willing to let them do so, in clear violation of the Prime Directive. The crew of the Enterprise sides with the natives, putting their own futures in doubt. The resolution reveals a surprising relationship between the antagonists and the protagonists, making one reevaluate the meaning of family.
