Plot Synopsis

Because of her beliefs, impassioned environmental activist Emily Booth has lost her son, Caleb, in a bitter custody battle, and the loyalty of her father, Oliver, the avaricious owner of Global Oil. Just when it couldn't get worse, she discovers, with the aid of former oil analyst Matthew Cooper, that her father's clean drilling record is a sham. When the company's state-of-the-art laser drill accidentally reaches a dangerous mass of magma, it unleashes a series of tremors that rock the small town of Maple Glen. Then, the unthinkable becomes a reality -- a volcanic eruption that blackens the sky in ash, spreading panic and death and trapping young Caleb in the devastation. But, as Matthew fears, this is just the beginning of a domino effect that carries catastrophic worldwide implications -- a connected volcanic system stretching from Yellowstone to Indonesia that, in a perfect storm of eruptions, could literally wipe out the planet. As Emily struggles to find her son, Matthew figures out how to stop the global eruptions already starting to rumble across the world -- he wants to puncture a new hole with sonic explosions and channel the magma into the ocean. It's a suicide mission, but it's the only answer to an extinction-level event only hours away from swallowing the Earth.
