Sound of Horror

Plot

In the Greek countryside, archaeologist Dr. Pete Asilov and Professor Andre attempt to detonate dynamite in an abandoned mountain cave, uncovering petrified eggs in the blasts. Taking one they fail to notice another had rolled off and hatched, releasing a reptilian creature that vanishes. Andre lives in a nearby villa with his orphaned niece Maria and their superstitious Greek housekeeper Calliope who warns Andre of the dangers of monsters and angry spirits in the mountain, which he ignores.

Later, as Prof. Andre investigates his half of an ancient map that tells him there is gold hidden in the cave, his business partner Dorman arrives with his associates Stravos, Andre his driver and his girlfriend Sofia. They carry the other half of the map which tells them where to dig for the treasure. Further ominous clues, such as the decaying body of an ancient neanderthal woman, further enforce Calliope's warnings, but the men are determined to find the treasure. They discover the bones of a man who was likely buried to keep from divulging the secret of the treasure. As Stravos investigates the mummified corpse while alone, he is killed when the creature stalks up unseen and slashes him to death with its claws. Shaken by its horrific scream, the men resolve to return to the cave for the treasure, blaming Stravos' death on would-be thieves from the nearby village. They are proven wrong and are chased back to the villa and in the process Dorman is injured. Terrified of what might be hunting them, they forget the treasure and work up a plan to escape. While fetching water for coffee, Calliope is killed by the creature and the humans barricade themselves in the villa

Professor Andre, determined to see his niece safe, entrusts her with Pete who shares an affection with her and sneaks back to the cave in order to seal it. He is attacked, but not before he detonates the dynamite and blows the cave entrance shut. The next morning, believing themselves safe, the remainder of the group boards Andre's car he dubbed "Diana" and try to leave, but the engine floods. As they try to start it, the creature returns, forcing them back into the house. They are attacked by the creature who had snuck into the villa and are barely able to trick it outside, Andre notices a trail of clawprints leading from the kitchen and using flour to help track the creature, they injure it with hatchets and it flees. They return to Diana and are able to start her, however, the creature reveals itself to be on top of the car which forces them to pull over. Dorman ignites the fuel reserves in the back of the jeep, destroying himself and the creature in a massive ball of fire. The creature dead and the four remaining survivors safe, they start their journey back to town on foot.
