In a last-ditch attempt to escape from the island on which they have been shipwrecked for over fifteen years, the Professor constructs a rocket ship that takes the seven castaways for an unexpected trip into the far regions of outer space. During the flight, the rocket's solar panels become damaged, forcing the ship to crash-land on an unknown planet, which eventually becomes their new home. The series depicts the castaways' attempts to get back to Earth.
