In the near future, eight astronauts from five countries (four women and four men) undertake a mysterious six-year international space mission covering thirteen billion kilometres. With the eyes of the world upon them - everything they do is monitored, and every emotion they feel, scrutinized - they soon discover that their real assignment is not at all what they thought. The first 8 episodes of Defying Gravity aired on both ABC (in the US) and CTV (in Canada).
Some of these will be so obscure you've most likely never heard of them. Most were canceled after one season, or just a few episodes even. But I've seen them all, of course :3.
