Sound of Horror (1966) – Full Plot Summary & Ending Explained

Read the complete plot breakdown of Sound of Horror (1966), including all key story events, major twists, and the ending explained in detail. Discover what really happened—and what it all means.

In the Greek countryside, archaeologists Dr. Pete Asilov and Prof. Andre detonate dynamite in an abandoned mountain cave, uncovering petrified eggs amid the blasts. One egg is taken, but a second hatched unseen, releasing a reptilian creature that vanishes into the mountainside. Andre lives nearby in a villa with his orphaned niece Maria and their superstitious housekeeper Calliope, who warns of monsters and angry spirits haunting the mountain—warnings Andre largely ignores.

Later, as Prof. Andre studies his share of an ancient map that promises gold inside the cave, his business partner Mr. Dorman arrives with his associates Stravos, his driver, and his girlfriend Sofia Minelli. They possess the other half of the map, which points to the treasure’s exact location. Ominous clues continue to arise, including the decaying body of an ancient Neanderthal woman, strengthening Calliope’s warnings. Yet the men remain determined to dig for the riches. They also discover the bones of a man who was likely buried to keep the treasure’s location secret. As Stravos investigates the mummified corpse, the creature stalks from the shadows and slashes him to death with its claws. Shaken, the men blame would‑be village thieves and hurry back to the villa, where Dorman is injured in the process.

Terrified by what might be hunting them, they momentarily abandon the plan to leave. While fetching water for coffee, Calliope is killed by the creature, and the group braces themselves inside the villa. Determined to keep his niece safe, Prof. Andre entrusts her to Dr. Pete Asilov, who shares an affection with her, and Pete sneakily returns to the cave to seal it shut. He detonates the dynamite and blows the cave entrance, buying them time.

The next morning, hoping to slip away, they find the car’s engine flooded and the vehicle unusable. The creature returns, forcing them to barricade themselves inside. It finally breaches the villa, but a trail of clawprints leading from the kitchen helps them corner the beast; flour on the floor marks its path, and they strike it with hatchets, driving it back. They manage to restart the vehicle, only for the creature to cling to the roof, prompting a desperate decision. Dorman ignites the fuel reserves in the back of the jeep, sacrificing himself and the creature in a massive blaze. With the monster dead, the four survivors begin walking back toward town, hoping to elude the mountains’ menacing reach.
