The Jupiter 2 lands on a planet Dr. Smith mistakenly believes is Earth. When Smith is lured out of the ship by cyborgs masquerading as earthlings, the Robot saves him - and the family - in the nick of time.

Will comes up with an idea for a two-man ship that can travel to Earth. But when Dr. Smith hijacks the ship, a crash landing finds Will and Smith trapped in a jungle, pursued by a bush creature.

A friendly little dog survives the crash of a space capsule and leads Professor Robinson and Don West to Judy, just in time to save her from the claws of a giant hairy mutant.

A strange galaxy tribunal imprisons the family, and attempts to try the crew members for crimes committed in outer space. The Robinsons are vindicated, while Smith is excused by reason of insanity.
