In a small and quiet California town, a mysterious phenomenon begins to unleash chaos and destruction. A group of geologists, while exploring rock formations, discovers a strange type of mineral that seems to possess a life of its own. When they take a sample to their laboratory, the researchers realize that anything that comes near this mineral is affected by a strange crystallization process, transforming into a monolithic structure. The situation becomes dangerous when the monoliths start to grow and multiply, devouring everything in their path and leaving a trail of destruction.
Among the protagonists, a young geologist and his girlfriend must join forces with an eccentric scientist and a local veteran to try to stop the expansion of these creatures. As the plot unfolds, the characters find themselves caught in a race against time, trying to uncover the origin of the mineral before the monoliths become a lethal threat to humanity. The horror escalates when they realize that time is not on their side: with each passing moment, the danger intensifies, and the town teeters on the brink of annihilation.
In this captivating blend of science fiction and horror, the struggle for survival turns into a series of tensions and unexpected revelations, where the true monster may not be the mineral itself, but rather our own curiosity in the face of the unknown.
