Sword and sandal nonsense as the son of Hercules, Argolese (Dan Vadis) saves beautiful princess Telca (Spela Rozin) from a lion and then goes on a quest to kill a rather ropey dragon in order to win Telca's hand from her father King Tedaeo (Ugo Sasso) - the King is hard to please obviously.
Argolese completes this task but when he gets back to the village he finds everything has been burned to the ground and everyone now prisoners of the evil Demulus - except the rather annoying Babar (Jon Simons) who becomes Argolese's companion / comic relief.
Argolese goes to the secret mountain lair of the Demulus, ending up captured himself after various violent antics in endless similar looking dungeons. He defeats elephants in an epic test and saves the life of the Demulus Queen Ella (Carla Calo). Argolese joins the Demulus (though Telca and the others remain slaves). Then the evil Melissa (Marie Flore) slays Ella to take over as Queen for herself...
So it is a lot of campy fun, if not very coherent. Argolese is suitably buff and has ample opportunities to show his strength throwing rocks and hauling chains. Melissa plays a good role, gorgeous and evil.
