Even if you do not know anything about earthquakes, you surely know the fault of San Andrés, one of the most active seismic points on the planet. In the tape the speech returns to make of his and it triggers a earthquake of magnitude 9, which is a true barbarity.
Due to the disaster, Ray travels to San Francisco. He is a pilot of a rescue helicopter and with him travels his ex-wife, Emma. Both go from Los Angeles to the city of the earthquake in order to find their daughter Blake, who is in San Francisco.
The road is not easy since everything is broken in its path. They think that civilization as they knew it still exists, but the truth is that the earthquake has ended with her at once.
On their journey you will see that everything they believed in is suddenly and very quickly disappearing, perhaps too much.
