A Federation team are unobtrusively observing life on the remarkable world of Ba'ku, where 600 peaceful inhabitants enjoy the planet's youth-preserving qualities. However, forces within the alliance want to repatriate the population so that the planet's resources can be exploited more intensively. Captain Jean-Luc Picard (Patrick Stewart) leads his crew in an effort to protect Ba'ku's residents and thereby honour the Federation's Prime Directive: non-intervention in the development of other civilizations.
