Steve, Benny, Andy, and Ed are yet another bunch of guys who discover a remote island populated with beautiful women. After their plane crashes in the ocean during a WWII bombing mission, they manage to reach an atoll populated with women descended from Druids - and the marauding Neanderthal men who keep bugging them. Steve and company earn the ladies’ trust, and everybody starts falling in love with everybody else. But High Priestess Sandra does not approve, and tries to dispatch the fellas to the vicious prehistoric creatures and man-eating vegetation. Then a volcano erupts.
