A century ago, scientists theorised that a habitable planet existed in a nearby solar system.
Today, ten astronauts will leave a dying Earth to find it. Four are decorated veterans of the 20th century's space-race. And six are teenagers, graduates of the exclusive Dalton Academy, who've been in training for this mission for most of their lives.
It will take the team twenty-three years to reach Terra-Two. Twenty-three years spent in close quarters. Twenty-three years with no one to rely on but each other.
Twenty-three years with no rescue possible, should something go wrong. And something always goes wrong.
