When the ocean suddenly turns solid in the small coastal town of Harbor Point, mechanic Daniel Mercer discovers that Earth is actually an ancient planetary machine designed by an alien civilization to stabilize reality itself. As a catastrophic failure opens a tear in the fabric of the universe, Daniel, engineer Maya Torres, and the people of the harbor work alongside alien repair beings to restart the buried planetary engine before entities from beyond reality consume the fracture. By combining human ingenuity with alien technology, they manage to jump start the engine and save the planet, proving that humanity has unknowingly become part of the system that keeps the universe intact.
