Synopsis
Amoeba-like aliens crash-land on a far-flung island in the South Pacific. Their plan to conquer Earth? Generate towering versions of native sea creatures. Soon, a supersized squid, a colossal crab, and a tremendous turtle are romping and stomping their way across the island, with hapless humans caught in their midst, in this fantastical kaiju extravaganza from genre master Ishiro Honda.
