A 36-foot-gorilla escapes from an oil tanker off the coast of Korea. After battling with a giant great white shark, the ape reaches land and destroys several buildings and attacking a giant python (the snake's origins are never revealed) before finding and kidnapping an American actress named Marilyn (Joanna Kerns). The military eventually corners and kills the ape, prompting one observer to comment, "He was just too big for a small world like ours!"
