A young woman falls down a hole and ends up discovering dinosaur eggs. A geologist with an interest in palaeontology discovers that a plesiosaur is terrorising his old home town, soon there are pterodactyls as well! And the humans are their prey...
Somewhat different for a kaiju film, with a bit more graphic violence than the usual cartoon like mass destruction of model buildings.
It isn't a very good film though with a confusing, slow moving but rather generic storyline. The best parts about the film are it's late 1970s cool feel (at times) and a Japanese funk soundtrack.
