Zordar's space fortress launches an assault on the Argo, heavily damaging it and injuring several of its crew. As the Star Force watches helplessly, Zordar attacks the Earth. Meanwhile, Trelaina uses her life force to bring Mark Venture back to life. Derek Wildstar orders the crew evacuated from the Argo. He boards the last remaining evacuation ship, but activates its autopilot and jumps off at the last minute. On board the Argo, he prepares it for its final trip -- a collision course with Zordar's ship. Suddenly, he sees Nova, who decided to remain to help him. As Wildstar and Nova steer the Argo toward Zordar's ship, they receive a communication from Trelaina, who is holding an unconscious -- but alive -- Venture. Trelaina returns Venture to the Argo, then says that Wildstar doesn't need to sacrifice the ship; she will fight Zordar. When Trelaina appears, Zordar stops his attack and tries to retreat, but Trelaina destroys his ship, sacrificing herself in the process. Wildstar and Nova salute Trelaina, and the Argo returns to Earth.
