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.

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.
