The crew faces their own demons and must overcome their own obstacles to continue their mission. This leads Data to return to his creator to better understand emotions. Worf must accept his Klingon heritage and face his former family. A power struggle threatens the Federation as the Romulans try to make peace with their universe and the Klingons deal with a potential successor to their empire. Political relations are strained within the Enterprise as a rogue ship attacks former enemies of the Federation, ultimately leading up to a civil war where one member of the Enterprise must decide where his loyalty lies.

Mentre Riker cerca di salvare l'Enterprise e la Terra da una potente razza aliena, la vita del Capitano Picard è in bilico. L'equipaggio affronta i propri demoni e deve superare i propri ostacoli per continuare la propria missione. Ciò porta Data a tornare dal suo creatore per comprendere meglio le emozioni. Worf deve accettare la sua eredità Klingon e affrontare la sua ex famiglia. Una lotta per il potere minaccia la Federazione mentre i Romulani cercano di fare pace con il loro universo e i Klingon affrontano un potenziale successore del loro impero. Le relazioni politiche sono tese all'interno dell'Enterprise quando una nave canaglia attacca gli ex nemici della Federazione, portando infine a una guerra civile in cui un membro dell'Enterprise deve decidere a chi riporre la sua lealtà.

Wesley Crusher udaje się do Akademii Gwiezdnej Floty, Data spotyka się ze swoim stwórcą, a załoga wypadowa teleportuje się na pokład okrętu Borga.
