The Captain (Vincent Price) rules the city, having been trapped there a hundred years ago with his crew of smugglers. For some reason they do not age in this lost Atlantis with mysterious pumping technology and Babylonian artwork. However the end is nigh as a volcano may erupt any moment and destroy everything...
Although the film can be a bit slow at times the film covers all the best "lost world" film tropes perfectly with some impressive set design which includes reproductions of Sumerian art. Vincent Price steals the show with his wonderfully dark and ruthless Captain. As for the rest of the acting it is passable though John Le Mesurier is good as a priest trapped in the lost world.
