Star Trek: Final Frontier takes places in the future of the Star Trek universe, approximately 150 years after the last events seen in the Next Generation era. This setting allows us to draw from Star Trek's rich past, but also to establish a new continuity that viewers can enjoy without detailed knowledge of decades of Star Trek history. The following summary provides a background for what happened in the time between Nemesis and Final Frontier. These events aren't portrayed in Final Frontier, but their echoes play heavily into the focus of the story:
In the wake of a vicious attack, warp travel has been rendered useless throughout much of Federation space. The detonation of multiple Omega devices has ripped subspace apart, marooning a handful of Federation worlds in their own systems, destroying key starbases, and stranding some Federation citizens decades of sublight travel away from their nearest neighbors and the protection of Starfleet. After investigating the attacks, the Federation discovered evidence of Romulan involvement and, desperate to retaliate, immediately declared war. The second Romulan war began, with the Romulans denying any involvement in the devastating Omega attacks.
With large sectors of space impassable at warp speed, the war quickly devolved into the 26th century equivalent of trench warfare, with heavy losses on both sides and little advancement for either force. A truce was reached, and the once mighty Federation retreated behind its borders to concentrate on rebuilding its worlds, strengthening its core systems, and ensuring that such an attack never occurs again. Starships once responsible for exploring the galaxy and maintaining diplomatic relations with non-Federation worlds were recalled to patrol the borders, and the scientific mandate of Starfleet was abandoned in favor of isolation and protectionism.
Yet there are those in Starfleet who know that humanity was meant for more, and that our foray into the stars was borne not of a desire for power but for knowledge and adventure. Captain Alexander Chase of the U.S.S. Enterprise is one of these men, and he's about to make a decision that will set Starfleet back on the right path...
