"The lives of all our people will be in danger.
After a brief introduction to Gamera we are transported to a remote island where a small group are hunting an opal stashed in a forbidden cave. Upon retrieval one of the gang betrays the others stranding one of the gang on the island. There an islander tell's the stranded man that their opal is not really a jewel and they have to retrieve it! But they are too late as a lizard, Barugon, hatches and sets about destroying Kobe and in turn attracting Gamera...
This creature feature was bought by AIP who Americanised it for television, presenting a monster not as compelling as Godzilla, but with a nice crime drama sub-plot.
