Plot:
As some gangsters are breaking into a place. Misaki, one of them shots himself and is promptly run over by a car. However, only
his clothes remain.
The police start investigating what happened to Misaki, who left a bag of rugs behind. The police question Mr. Chin to try to get him
to ID the man who got the drugs.
Checking Misaki's apartment, they just find his girlfriend, Shitako. They question her but don't get anything.
That night, Shitako meet Professor Misada. The cops take him in. The professor explains Misada may have been exposed to
radiation.
The gangsters keep hassling Shitako assuming she knows where Misaki is. He leaves. The cops re-question her and believe
that Misaki stopped by to visit her. Professor Misada finally gets to question her.
Later, Professor Misada takes the chief to meet some guys who've melt the dissolving men. Cut to the flashback, a boat of fishermen
find a deserted ship. They board it and don't find anybodies just several piles of clothes. A pile of goo dissolves one of the fishermen,
and his body is gone. H-Man gets another victim. Only 2 men are left and get back to their ship.
Professor Misada shows the chief the deserted ship's log book and takes him to a scientific example which is to show his idea. A
frog exposed to radiation melts, but the frog goo is still alive. Chief doubts all this scientific mumbo-jumbo.
Professor Misada finds a life preserver from the deserted ship which the chief discounts.
Shitako wants people warned about the killer goo. The chief, professor, and her talk. She agrees to ID the gangsters at the nightclub
so they can be arrested. At the club, the cops start busting the mobsters. The goo makes an appearance and starts killing and absorbing
people. Ishiro, a mobster, removes his clothes to fake his death.
More melting, exploding toad science fu ensues. The goo eats the other frogs and is drawn to human flesh.
Let the newspaper montage ensue. As scientists brief everyone that only fire or electricity can stop the goo. Finally, chief believes
Professor Misada.
Shitako is about to go on a date with the professor when she's kidnapped by Ishiro. Misada chases but loses them.
The city starts to evacuate. Ishiro takes Shitako into the sewer where he has hidden the drugs. They hear the police in the
sewers. He has her take off her clothes to fake her death.
The police prepare to destroy the goo. Misada heads to the sewer to look for her. The police have the operation ready to be
implemented. Let the flaming sewer ensue. Chief heads to help the professor.
The goo gets Ishiro. Shitako is running in terror and runs right into Misada and the chief. The H-Man gets para-broiled. Out of
the sewer, Chief, Misada, and Shitako head to the hospital.
