Ghidorah, the Three-Headed Monster

Police Detective Shindo (Yosuke Natsuki) is assigned to guard Princess Selina Salno of Selgina (Akiko Wakabayashi) during the Princess' visit to Japan, due to a suspected assassination plot. Although Shindo is smitten with Selina's photograph, her plane never makes it to Japan, as it is destroyed by a bomb en route. At exactly the same time, a meteorite shower draws the attention of Professor Murai (Hiroshi Koizumi), who, along with his team of scientists, strikes out into the wilderness to examine the largest of the meteors, which has magnetic properties.
