Face to face with Klingon vessels, the U.S.S. Shenzhou prepares for the possibility of war if negotiations fail. Amidst the turmoil, Burnham looks back to her Vulcan upbringing for guidance.

With tensions and stakes high as Starfleet continues in their efforts to end the war with Klingons, Burnham begins to settle in to her new position aboard the U.S.S. Discovery.

The U.S.S. Discovery crew is intrigued by new addition, Lt. Ash Tyler. Sarek seeks Burnham's help, rekindling memories from her past. Admiral Cornwell questions Lorca's tactics.

The U.S.S. Discovery is tasked with a high priority mission to planet Pahvo and learn the science behind the Klingon's cloaking technology.

Bypassing Starfleet's orders, Lorca uses the U.S.S. Discovery crew's ultimate asset, the ship itself, in an effort to end the war with the Klingons once and for all.
