Season 3
A stark contrast to other seasons, Enterprise’s third season features a season-long story arc stemming from the second season cliffhanger. Desperate to stop an inevitable second attack on Earth, ship and crew transverse the dangerous Expanse in a critical effort to track down the Xindi – a factioned group of multiple subspecies. Ultimately, they come to discover that the threat extends further than the Xindi, with repercussions extending beyond their own universe and timeline.
