Tilly and Adira lead a team of Starfleet Academy cadets on a training mission that takes a dangerous turn. Meanwhile, Burnham is pulled into tense negotiations on Ni'Var.

Burnham and Book race to evacuate a group of stranded colonists in the anomaly's path as one of the Federation's brightest scientists comes aboard the U.S.S. Discovery to do high-stakes research with Saru and Stamets.

Seeking answers, the U.S.S. Discovery ventures into a subspace rift created by the Dark Matter Anomaly. Meanwhile, Book faces a strange visitor from his past.

Following a hunch, Captain Burnham tracks Book to an old haunt from their courier days and gets drawn into a high-stakes competition for a powerful weapon.

Captain Burnham and the U.S.S. Discovery race to stop Book and Ruon Tarka from launching a rogue plan that could inadvertently endanger the galaxy.

Captain Burnham and her crew must go where few have gone before: beyond the Galactic Barrier. Meanwhile, Book learns the truth of what drives Ruon Tarka.

While Captain Burnham leads an away mission to a planet that was once home to the aliens responsible for the DMA, Book and Tarka secretly infiltrate the U.S.S. Discovery.

As the DMA approaches Earth and Ni'Var, Captain Burnham and the crew of the U.S.S. Discovery attempt to make First Contact with the powerful species responsible before it's too late.

As the DMA approaches Earth and Ni'Var, and with evacuations underway, Burnham and the team aboard the U.S.S. Discovery must find a way to communicate and connect with a species far different from their own before time runs out.
