The crew of Discovery is sent to retrieve a mysterious artifact from an 800-year-old Romulan vessel, but find that they are not the only ones on the hunt. Meanwhile Saru considers his future.
With help from Book, Captain Burnham and the crew search the remnants of an extinct civilization for the next clue to a mystery that could reveal the secrets of creation itself. Book makes contact with the competition, and learns a starting secret about Moll and L'ak.
The hunt takes Discovery to Trill where Burnham, Culber, and Book face a dangerous test to obtain the next clue. Meanwhile Adira reconnects with Gray, and Saru learns that his relationship with T'Rina might hurt her politically.
On the way to the next clue, the U.S.S. Discovery is sabotaged by a mysterious weapon, leaving Captain Burnham, Rayner, and Stamets as the only crew members who can possibly save the ship in time. (Paramount+)
