In 2154 Enterprise returned to Earth after defeating the Xindi threat, and its crew found a world that honored them but had grown suspicious of aliens.
The crew were greeted as heroes, yet the Xindi attack had left many humans resentful of other species. Phlox was attacked during shore leave, and T'Pol faced pressure from Starfleet and from her own people.
Archer, struggling with what he had done in the Expanse, spent time recovering in the mountains. T'Pol traveled to Vulcan with her mother and agreed to marry Koss. The homecoming showed how much the mission had changed the crew and the growing tension between Earth and its neighbors.
