Plot:
Starfish shaped aliens have a plan and must contact the Japanese scientist, Professor Kimura.
The most ridiculous looking aliens ever...
In Japan, life goes on like usual. Professor Kimura and a reporter talk about the increase spottings of flying saucers.
At the observatory, a flying saucer is spotted. Suddenly, the city is plagued with power blackouts.
Professor Kimura heads home and greets his daughter. The good scientist must have empirical evidence before he even contemplates anything about flying
saucers. After spotting one saucer himself, he heads to the observatory for more data.
Newspaper montage ensues. Reporters question the astronomers after saucers are seen all over the world. Kimura wants to use a rocket top photograph the saucers.
That night, some Starfish aliens emerge from the water and d scare some sailors. Noh theater and drunken office workers kicking back ensues.

Later, the cops bring a scientist to a sample alien slime. At the observatory, the photos are studied.
Scientist guy checks with Kimura. A strange glowing ensues in the apartment that freaks out daughter when she spots a Starfish alien.
Another newspaper montage ensues. The World Congress has ordered all the nations to quit launching anything into space but will try to shoot down a saucer.
Suddenly, a dance number pops up out of nowhere.
Why does a science fiction movie need many dance routines?
A Starfish alien appears and scares the lead dancer.
A saucer heads back to the alien satellite base. Humans consider the aliens as monsters. The new plan is for one of the Starfish aliens to transmorph into the duplicate of
a human, even has a picture of the dance lady. The human then could get in touch with Kimura. Let the Starfish to human transfiguration machine ensue.
The scientists are on a break. The saucers have disappeared. Scientist man and Kimura’s daughter tare taking a boat ride and find a body in the lake. Let’s call her Star
Dancer.
Back to the club which is doing the Ricky Richardo show at the Tropicana Club from I Love Lucy, dance lady faints when told about a woman who looks identical to

Dancer who disappears through a door.
Scientist examines Star Dancer’s fingerprints.
Star Dancer pays a visit to Matsuna. He is developing a formula for an explosive more powerful than A or H-bombs. She tears the formula up.
Later, Kimura and other scientists discuss how strange Star Dancer is and how could she understand Matsuna’s formula. They think she’s not human. Has no fingerprints
and cellular material from her matches the alien slime.
Star Dancer appears. She explains how her planet is in the exact opposite orbit of Earth. They developed Matsuna’s formula. The aliens came to Earth to save it and their
planet, Paira. A rogue planet from another galaxy will collide with Earth. They can use all of Earth’s nuclear weapons to alter the planet’s course?
The scientists warn people of the impending collision.
Idiot picnickers doubt the announcement.
Back at the observatory, the scientists hold a press conference. The World Congress has denied their petition. Kimura will go ahead and try to be as ready as possible. 15 more
days until planet R will be visible to the naked eye.
Newspaper montage ensues.
Kimura gives another press conference and mentions Matsuna’s theoretical explosive which could be used.
Saito wants to but Matsuna’s formula.
Everyone is waiting for Planet R to approach. The calculations lead to the conclusion that Planet R will collide with Earth in 50 days. The World Congress will reconsider Japan’s
proposal for using nuclear weapons
Panicked evacuation ensues.
Planet R is accelerating.
Saito has his lackeys kidnap Matsuna. Saito doesn’t believe in the Planet R collision but will get the formula at any cost.
Desert city ensues. Planet R is accelerating again and will hit Earth in 20 days. The World Congress finally approved the nuclear barrage.
The nukes are launched. Everyone waits and learns it didn’t move Planet R at all. Now, Planet R is 5 days away. Earth has been getting hotter. Animals keel over from the heat
or hide in holes. Tidal waves destroy model cities.
Some of the shelters begin to get flooded.
Matsuna is still tied up.
Star Dancer teleports to the shelter. They’ll be able to find Matsuna who has a ring that has a radio transmitter. The aliens have the equipment ready but just need Matsuna’s
formula.
Matsuna staggers into the shelter. The aliens have the missile ready. The final countdown sees the missile launched from the alien satellite base and blows up Planet R.
the animals return from their hiding places. The kids leave the shelter and celebrate.
Star Dancer returns to the base and returned to her Starfish alien form.
