Takuya's (Shinji Todou) sister Shinko (Izumi Oyama) pays a visit to her
friend Shimako, who lives somewhere in the country with her scientist
father ... and is attacked by a Snake Woman (of course, it's Shimako
herself under some terrible spell, but only we, the audience, know that).
Thank God Takuya's spider sense is tingling just in time and as Spider-Man
he is rushing to her rescue. He takes her to a hospital but keeps the
hospital's location a secret to everyone ... but when Shimako - in human
form - asks him where to visit his sister, he tells her. This is a problem
because Shimako is not only the Snake Woman, but she's also a hired
assassin by the Iron Cross Army ordered to kill Shinko. However, when she
sees how Takuya, a childhood friend of hers, takes care of Shinko, she is
overcome by human emotions and has second thoughts about her mission.
Takuya finds out that Shimako is actually the Snake Woman and that the
Iron Cross Army actually uses her father's house as their new headquarters
to build some kind of superweapon based on Shimako's father's findings.
When Takuya, as Spider-Man, enters the house though, he is attacked and
almost defeated by the Snake Woman and the Iron Cross Army's own Amazoness
(Yukie Kagawa) - when the Snake Woman switches allegiances and helps
Spider-Man chase away the Amazoness and their henchmen, even giving her
own life in the process. Then Spider-Man calls in his giant robot
Marveller to destroy the superweapon.
A handful of scenes that
are actually atmospheric accompanied by a very wild (though completely
unconvincing) Snake Woman costume - well, it's nothing great, but good
fun, Spider-Man style.
