The first half of the episode is a retelling of Yuri Leonov’s last flight – a married man working in the UN flight program who leaves his wife for another mission only to be unintentionally sacrificed for science when his flight was sent to investigate a gravitational anomaly. He claims that his last memory was of seeing the anomaly up-close before returning to Earth in the form of the alien invaders. The flashback includes some other interesting developments – the long-haired man who turned Ryu into a spy was Yuri’s mission commander on Earth named Colonel David Lawrence who also was a close friend of Yuri (and was coincidentally against using Yuri’s mission to investigate the anomaly).
