Joe and Eddie are fascinated by the bubbling mud pools and boiling geysers that dot the landscape around the lake where they're staying. They meet local geologist Rocky, who tells them about the cataclysmic 1886 eruption of Mt Tarawera - the volcano that casts a long shadow towards their holiday cottage. But Joe?s fascination turns to unease when ghostly sightings on the lake and dark rumblings from the Earth hint that the volcano is reawakening. Can he persuade Rocky, who puts his faith only in science, to sound a warning? As the mountain bursts into life and lava bombs rain down, the ghosts of Tarawera reappear.
