Arriving 930 years in the future, Burnham navigates a galaxy she no longer recognizes while searching for the rest of the U.S.S. Discovery crew.

Reunited with Burnham, Discovery heads to Earth to find out what has happened to the Federation in the last thousand years.

Burnham and Adira visit the Trill homeworld while Saru's efforts on the Discovery to help the crew reconnect yield surprises.

After reuniting with what remains of Starfleet and the Federation, the U.S.S. Discovery and its crew must prove that a 930 year old crew and starship are exactly what this new future needs.

After receiving a message from Book, Burnham and Georgiou embark on a rogue mission to find him, leaving Saru to pick up the pieces with Admiral Vance. Meanwhile, Stamets forms an unexpected bond with Adira.
