Co-created by Michael Taylor and Ronald D. Moore (Battlestar Galactica), the sci-fi drama revolves around the crew of the Phaeton, Earth's first starship. To endure the 10-year journey, the astronauts use virtual reality modules which allow them to assume avatars and explore self-created scenarios. But just as the mission is about to enter its critical go/no-go phase, a virus begins to infect the system and puts all of their lives on the line.
