Commander Michael Burnham of the Federation starship U.S.S. Shenzhou disputes her captain’s peaceful stance when their ship encounters hostile forces.

Escaping from the brig while the ship is under attack, Burnham joins the captain in an audacious plan to end a battle rapidly escalating into war.

Michael’s shuttle is intercepted by Captain Gabriel Lorca of the mysterious U.S.S. Discovery, who orders her to join a dangerous recovery mission.

Voq faces a powerful challenge in his pursuit of T’Kuvma’s agenda, while Michael discovers a possible solution to the ship’s propulsion difficulties.

When Lorca is kidnapped by the Klingons and imprisoned with an eccentric cell mate, the Discovery is assigned to rescue him despite Michael’s doubts.

Michael uses her connection to Sarek to help locate him after he is wounded in an assassination attempt. Lorca deals with an unexpected visitor.

A figure familiar to Lorca and Lt. Tyler from the Klingon prison ship attacks the Discovery, intending to deliver the ship to their former captors.

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.

While in unfamiliar territory, the U.S.S. Discovery crew is forced to get creative in their next efforts to survive opposing and unprecedented forces and return home.

The crew continues their guise, and Burnham is ordered on a merciless mission to end the resistance in hopes of returning home. Meanwhile, Tilly works on restoring Stamets’ neurofunction.

Burnham heads to the ISS Charon with a special “gift” for the Emperor. With the help of an unexpected source, Stamets gains clarity while trapped inside the mycelial network. Saru asks for L’Rell’s help.

Lorca plans to move forward with a coup against the Emperor, propelling Burnham to make a quick decision to save not only herself, but the U.S.S. Discovery.

Burnham and the U.S.S. Discovery crew are faced with the harsh reality of the war during their absence. In order to move forward, Starfleet must use unconventional tactics and sources to take their next action against the Klingons.

With Georgiou at the helm of the plan to end the Klingon war once and for all, the U.S.S. Discovery crew struggles to fathom and tolerate her hostile tactics. Memories of past hardships are rekindled within Burnham.
