2401: Just weeks after defeating a devastating joint attack by rogue Changelings and remnants of the Borg Collective, Starfleet and the Federation face a long period of recovery that requires replacing lost personnel and ships. While touring the U.S.S. Titan-A, which is just beginning an extensive repair-and-refit process that will take nearly a year to complete, newly promoted Captain Seven of Nine and her first officer, Commander Raffi Musiker, experience a bizarre temporal event which renders them both unconscious and sends Seven into a deep coma.
