With the disappearance of a Federation colony, the Enterprise warp speeds to action to uncover if the reason was political or something much more sinister. Along their travels, the crew must escort a scientist who may hold the key to a malfunction that places the crew in danger. Prime Directives are broken as Picard is taken for a god on a primitive world. The Romulans continue to notice Federation intrusion into the Neutral Zone and threatens war against the Enterprise. Things become much more complex as an old enemy stops by and Picard must decide if he should offer solace or choose to remain enemies as a precaution. All leading up to finally answering the motives of Starfleet and the Federation as the Enterprise continues on its mission to explore the galaxy.

Con la scomparsa di una colonia della Federazione, l'Enterprise entra in azione per scoprire se il motivo era politico o qualcosa di molto più sinistro. Durante i loro viaggi, l'equipaggio deve scortare uno scienziato che potrebbe contenere la chiave di un malfunzionamento che mette in pericolo l'equipaggio. Le Prime Direttive vengono interrotte quando Picard viene scambiato per un dio in un mondo primitivo. I Romulani continuano a notare l'intrusione della Federazione nella Zona Neutrale e minacciano di guerra contro l'Enterprise. Le cose diventano molto più complesse quando un vecchio nemico si avvicina e Picard deve decidere se offrire conforto o scegliere di rimanere nemico per precauzione. Tutto porta a rispondere finalmente alle motivazioni della Flotta Stellare e della Federazione mentre l'Enterprise continua la sua missione di esplorare la galassia.
