In the near future, earth`s fossil resources are about to be used up. In an
attempt to save the human race, scientists have begun building a gate,
through which faster than light travel will be possible - but only if there is a
gate at the destination to receive the travelers. The Robinson Family has
been chosen to travel to Alpha Prime - the only other inhabitable planet
known - at normal speed, ten years, cryogenically frozen. But Dr. Smith, a
sinister man, sabotages their spaceship, Jupiter 2, but is also betrayed by
his people. So, he has to work together with the Robinsons in order to
survive
himself. When Jupiter 2 is falling into the sun, the only chance to survive is to
activate the hyperdrive - without a gate at the other end. Soon, the Robinsons
are someplace really unknown, where they meet unfriendly silicon-based
space spiders, take in a little ape-like creature and name new star systems
after Bugs Bunny and Porky Pig. They have to reach Alpha Prime in order to
build the second gate, or earth's only hope is gone.
