The Rocketfellers can't wait to get home to the 25th century... except they can't. They're chased by bounty hunters, hidden in 2025, and befuddledly fitting into this might-as-well-be-ancient society. So this family does what it does best: Dad, Rae, and Rex go on a personal adventure, while Mom craves a return to the stars. And as for eldest son Richie? His mystery project could be their undoing.
