Barry investigates the fall of a meteorite outside of Central City, which turns out to be a spaceship from which aliens are emerging. Laila tells the team that the Dominators landed earlier in the 1950s, but then mysteriously flew away. Needing help, Barry assembles the original team of Arrow, Thea Queen, the Legends, and Supergirl. The team begins training at S. T. A. R. Labs, sparring with Supergirl to prepare for a battle against the aliens. Cisco reveals a message to Rip Hunter from Barry's future self that exposes Barry's manipulation of the timeline and how it affected the other team members. Oliver, Supergirl, Felicity, Martin, and Jefferson are the only ones who still trust Barry. The potentates kidnap the president. Supergirl leads most of the others in a rescue mission, but the Dominators kill the president and trap everyone with a mind control device. The controlled heroes return and attack the S. T. A. R. labs. While Oliver holds them back, Barry lures Supergirl to the device and manipulates her to destroy it, freeing everyone. The team decides to trust Barry again. Suddenly, Sarah, Ray, Diggle, Thea, and Oliver teleport away before Barry can intervene.
