This edition of Star Trek takes place during the 22nd century. Jonathan Archer (played by Scott Bakula) is the captain of the Star Trek Enterprise NX-01. He and his crew are charged with exploring the galaxy and along the way they come up against other races like the Klingons and Andorians. More dangerous than these species are the Xindi and Season Three preoccupied itself mostly with that storyline. Season Four, which was the series’ last, is made up mostly of stand-alone episodes that deal with interspecies relationships.
