Sci-fi drama. A team of eight astronauts, embarking on a six-year journey to explore Venus and other planets in the solar system, find their lives and destinies intertwined and carefully directed, not only by Mission Control officials on Earth, but also by an unseen force which is much closer and far more powerful.

Taboos are broken and lines are crossed as the personal and professional relationships on the Antares and on Earth continue to intensify, while the unseen power behind the mission begins to create both cellular and psychological transformations among the astronauts.
