Around 1930, a series of mysterious shipwrecks occurred off the coast of the Bahamas. Taking the situation seriously, the governments of the United States and neighboring countries dispatched an investigation team to "Green Island," located in the waters where the incidents were frequent. Investigations revealed that the island was an ancient primeval forest consisting of flora from 100 million years ago, but the team members were soon attacked by swarms of prehistoric creatures thought to have been extinct.
