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 kilometers.
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.
