This begins with a bomb threat on an airplane, which is soon hijacked, with pilot Ei Sugisaka (Teruo Yoshida) and stewardess Kuzumi Asakura (Tomomi Sato) held at gunpoint. As the plane changes course to Okinawa, a UFO smacks into their flight path and causes them to crash, killing everyone except Mrs. Neal (Kathy Horan), Senator Mano (Eizo Kitamura), weapons dealer Hirofumi Tokiyasu (Hideo Ko) and his wife Noriko (Yuko Kusunoki), space biologist Professor Saga (Masaya Takahashi), psychiatrist Dr. Momotake (Nobuo Kaneko), the boy who called in the bomb threat and the hijacker, who takes Kuzumi and makes his way toward the UFO, which splits his head open and sends a blob into his body.

Dr. Momotake is attacked by the teenager and knocked off a cliff, where he finds the hijacker, who drains the blood from his body. It soon kills Tokiyasu and possesses Noriko, speaking with the voice of an alien race through her body. The Gokemidoro have invaded Earth and no human will survive. She falls off a cliff and instantly turns into a corpse.

The survivors lock themselves in what’s left of the plane, but the teenager explodes his bomb, allowing the hijacker to kill Mrs. Neal. Mano locks all of them out of the plane as they set the hijacker on fire, but even that won’t stop the alien, which kills everyone but Sugisaka and Kuzumi, who find every car empty on a highway and every human dead.

Nearly every character — other than the survivors — is a horrible person and does just as much to kill people as the aliens. As it is, even when the two characters survive, they only will live long enough to see the invasion begin, unless a miracle occurs after the credits.

If you ever wondered why the sky is so red when the Bride lands in Japan during Kill Bill Volume 1, this movie is the reason. Quentin Tarantino is a huge fan of it.

Directed by Hajime Satô, who also used the Westernized name Terence Ford and also  directed The Golden Bat, this was based on the tokusatsu series Gokemidoro. This feels like The Blob meets The Thing and then space vampires in a world where everything is neon and even birds realize that things are hopeless and commit suicide. 1960s Japanese science fiction horror made by people that know that mankind is hopeless because while other filmmakers made movies about the horrors of nuclear war, they had already survived it and knew everything was darkness.
