After 13 years of space travel, now far past the orbit of Pluto, the crew of the spaceship Explorer has been mysteriously cut off from communication with Earth. In light of Earth's sudden silence, something about Explorer's mission-to find and colonize an Earth-like planet-doesn't ring true anymore. The crew grows restless, and amid the turmoil, one of the meta-humans on board discovers a secret, final message from Earth that reveals shocking news. A crewmember disappears, and ship wide paranoia ensues. Will the Explorer crew band together or turn on themselves? And what is the true nature of their mission?
