With the departure of first officer William Riker and ship's counselor Deanna Troi, Picard has to replace two of his most trusted advisors. A Vulcan is granted the commission of ship's counselor. Logical and pragmatic, T'Lana is a highly decorated member of Starfleet who served with distinction during the Dominion War. For his Number One, Captain Picard has only one candidate: Worf.

The captain is looking forward to putting the shadows of war behind him, shaping his new crew, and returning at last to being an explorer. However, the Klingon refuses the promotion. And Picard senses that his new counselor does not approve of Worf.

Starfleet hands the Enterprise a simple assignment perfect for a shakedown cruise. Picard is confident that this is all he needs to bring his crew together. Before the mission commences, the captain once again hears the song of the Borg Collective. Admiral Janeway is convinced that the Borg have been crushed and are no longer a threat. Picard knows that she is wrong, and if he doesn't act immediately, the entire Federation will be under the domination of its most oppressive enemy.
