French Hercules is flung headlong into the world of the sixth dimension. This kingdom is ruled by the horney midget King Fausto (Herve Villechaize) and inhabited by dancing frogs, maidens in bikinis, robot-like boxers (The Kipper Kids), and degraded beings of all kinds.
Will the robust Queen Doris destroy the King in a fit of jealousy? Will Frenchy suffer the same fate as the other imprisoned damsels? Will Flash and Gramps reach Frenchy in time to rescue her from the depths of the Forbidden Zone?
