The hidden history of the Star Trek universe is revealed in this new series charting the seventy years between Captain Kirk's disappearance and the beginning of The Next Generation. Nearly a decade after Captain Kirk vanished, his protege, Captain Hiraku Sulu of the USS Excelsior, leads a dangerous mission into uncharted political waters. Unprecedented peace talks with the violently xenophobic Tholian Assembly trigger a deadly confrontation aboard the Excelsior. Now Sulu and his crew - including Chekov, Rand, Chapel, Tuvok, and Akaar - are thrust into an unexpected conflict between the Tholians and a mysterious new enemy, the Neyel... whose origins, if revealed, could lead to war with Earth itself. As the Tholians weave a web of vengeance, the Excelsior is flung beyond the galaxy and the crew discovers the hidden truth about the alien Neyel, forcing Sulu to question where his responsibilities lie - with the fragile peace he must preserve, or with the victims of his own world's tragic past.

After the disappearance of Captain James T. Kirk, and before Captain Jean-Luc Picard took the helm of the Enterprise, the Federation and the Romulans clashed head on in a confrontation that would change the course of history.

To the Cardassians, it is a point of pride. To the Klingons, a matter of honour. But the eighteen-year cold war between these two empires—euphemistically remembered in later years as the Bretaka Nebula Incident—creates a vortex of politics, diplomacy and counterintelligence that will define an age, and shape the future. What begins as a discovery that would enable the Klingon Empire to reclaim a lost piece of its past becomes a prolonged struggle with the rapidly expanding Cardassian Union, which has claimed dominion over a region of space that the Klingons hold sacred. Enter the Federation, whose desire to preserve interstellar space leads Ambassador Curzon Dax to broker a controversial and tenuous peace—one that is not without opponents, amongst them Lieutenant Elias Vaughan of Starfleet special ops. But there are wheels within wheels to the drama unfolding in the Betreka Nebula. Within the shadowy rooms of the Cardassian Obsidian Order, Klingon Imperial Intelligence, and even the Romulan Tal Shiar, secret scales are being balanced—and for every gain made for the sake of peace, there will come a loss.

Captain Rachel Garrett and the crew of the Enterprise become embroiled in a web of extortion, abduction, and murder when a remarkable archaeological find that offers possible revelations about the Cardassian civilization threatens to ignite a struggle between the Qatala and its rival, the fledgling Orion Syndicate. Original.

In the wake of the Tholian attack that nearly cost him his life, Kyle Riker becomes the target of an apparent conspiracy within Starfleet Command. Forced off the Earth, and even beyond Federation territory, danger is never far off, not even a backwater world is safe.

A lethal Romulan-trained agent turns against her paymasters in order to prevent them from unleashing a terrifying biological holocaust. Admiral Uhura of Starfleet Intelligence sends the young Romulan to investigate with a team of special operatives: Dr Beverley Crusher (Star Trek: The Next Generation), a young Lieutenant Benjamin Sisko (Star Trek: Deep Space Nine) and the Vulcan Lieutenant Tuvok (Star Trek: Voyager).
