Before they reach their destination, an alien robot breaches the Resolutes hull. Forced to evacuate the mothership in the short-range Jupiter spacecraft, scores of colonists, among them the Robinsons, crash on a nearby habitable planet. There they must contend with a strange environment and battle their own personal demons as they search for a way back to the Resolute.
