Star Trek: Discovery

Season premiere. After answering a distress signal from the U.S.S. Enterprise, the U.S.S. Discovery welcomes aboard Captain Christopher Pike (Anson Mount) and begins a new mission to investigate the meaning behind seven mysterious red signals. Michael Burnham grapples with her past growing up on Vulcan with her foster parents and brother Spock.

A new signal appears, prompting Stamets' emotional return to the mycelial network and leading Burnham, Pike and Owosekun to a pre-warp planet, where they face a complex ethical dilemma. Tilly's overeagerness lands her in trouble but when the planet - and Discovery's landing party - are threatened, her curiosity may be the one thing that can save them.

Burnham and the crew navigate a dangerous alien landscape in a race against time to save Tilly's life, but Stamets is not at all prepared for what they find in the process. Section 31 is assigned to help track down Spock, much to Pike's dismay.

Spock and Burnham head to Talos IV, where the process of healing Spock forces the siblings to confront their troubled past. Stamets desperately tries to reconnect with an increasingly disconnected Hugh, while Tyler struggles to shed the crew's suspicions of him due to his past as Voq.

When the Discovery crew infiltrates Section 31's headquarters, suspicions arise that the crew may have a traitor in their midst. Burnham tries to help Spock but her efforts don't go as planned.

Burnham is stunned when she learns her ties to Section 31 run deeper than she ever fathomed. Armed with the identity of the Red Angel, the U.S.S. Discovery goes to work on its most critical mission to date.

Burnham receives the reunion she's been longing for, but it doesn't go quite as she imagined. Georgiou and Tyler sense a disturbing change in Leland.

A fourth signal leads the U.S.S. Discovery to an insular world, where Pike is forced to make a life-changing choice. Burnham and Spock investigate a Section 31 ship gone rogue, leading to a discovery with catastrophic consequences.

When the U.S.S. Discovery's crucial mission does not go according to plan, Burnham realizes what must ultimately be done. The crew prepares for the battle of a lifetime as Leland's Control ships get closer.

Season two finale. The U.S.S. Discovery battles against Control in a fight not only for their lives but for the future, with a little help from some unexpected friends. Spock and Burnham discern vital new connections between the red signals while Burnham faces one of life's harshest truths: the right decisions are often the hardest to make.
