The Ultimate Vampire Resource and Directory

After Yata is lost at sea, his brother Ryota steals a yacht with his two friends and a bank robber. The crew runs afoul of the giant lobster Ebirah, and washes up on the shore of an island, where a terrorist organization manufactures heavy water for their purposes, as well as a chemical that keeps Ebirah at bay. The organization, known as the Red Bamboo, has enslaved natives from Infant Island to help them, but the natives hope to awaken Mothra to rescue them. In their efforts to avoid capture, Ryota and his friends, aided by a beautiful native girl, stumble across Godzilla in a cliff side cavern. The group devises a plan to defeat the Red Bamboo and escape from the island. In the process, they wake Godzilla using a lightning rod, retrieve the missing Yata, free the enslaved natives and destroy the base, but in the process the island becomes unstable. As Godzilla fights Ebirah, the natives summon Mothra to save everyone, and everyone is saved.
