Bad, even for a Japanese monster movie!

An expedition in the South Pacific lands on a tropical island where the natives worship the mysterious deity Gappa. An earthquake opens up an underground cavern and a baby reptile is discovered inside. The natives warn the foreigners to leave the hatching alone, but they don't listen and take it back to a zoo in Japan. Soon after, Mom and Dad Gappa start smashing Tokyo looking for their kidnapped child.
