The People That Time Forgot

Ben McBride (Patrick Wayne) leads an expedition to the lost island of Caprona to search for his friend Bowen Tyler (Doug McLure). After their plane is attacked by a Pterodactyl, they set off through the strange country on foot. A beautiful native girl Ajor (Dana Gillespie) tells them Tyler has been captured by the Na-Gas, a savage tribe who sacrifice prisoners to their Volcano God. They in turn are captured and held prisoner in the City of Skulls, built entirely from Human Skulls.
