A mother rushing to rescue her only child.

A worried son desperately trying to get his parents out of harm's way.

A geologist trying to save them all.

Thirty years after surviving a landslide that killed his entire community, Tim is a geologist with the US Geological Survey. When he realizes that Mt. Rainier is about to erupt, he is determined to warn everyone about the imminent danger, only to have his words fall on deaf ears.

Jordan is one of the few who takes the warning to heart. Worried for the safety of his elderly parents, he urges them to evacuate. However, they seem unconcerned - Mt. Rainier hasn't erupted in hundreds of years after all, and it's too far away to be dangerous.

After dropping her son off at school, 911 dispatcher Teresa goes to work, only to start receiving distressing calls about the eruption. Terrified and torn between helping many and running to save her only child, she soon finds that the decision has been made for her.

As deadly as lava, landslides, and constant ash raining down are, they're not the only threats. Opportunists are another... and millions of people driven insane by fear might be the biggest danger of all.
