60 years worth of shows, novels, books, games, and movies. The original series follows the USS enterprise, flagship of the United federation of planets, as it explores new worlds. Most episodes are self-contained, where they face off against some threat or mystery on the planets they visit. The sequel series star trek: the next generation follows a later enterpise from 200 years after the first one, with roughly the same formula for episodes. There's also Deep Space Nine, centering on a space station near the newly liberated planet Bajor and a newly discovered wormhole to the distant gamma quadrant of the galaxy. This series focuses on many episodic adventures like before, mostly from visitors to the station bringing some curiosity or scheme, but it also has longer plot lines focusing on diplomacy and peace keeping, ultimately leading to the dominion war, a battle for control of the alpha quadrant with the most powerful force in the gamma quadrant, the dominion. Voyager is another sequel, following the star ship voyager after a powerful alien sends it to the unknown delta quadrant, and they have to survive and find a way home so far from everything they know. Enterprise is set well before the original series, and follows the early years of the Federation through it's first flagship. There's also discovery and strange new worlds, set shortly before the original series.
