When colossal earthquakes erupt along the San Andreas Fault, Los Angeles hovers on the brink of destruction. As a mass evacuation of the city is ordered, a few survivors find themselves left behind, roaming the streets with a group of dangerous convicts who escaped from prison during the tremors. Amidst the chaos, Calvin Hopkins is stranded in the disaster zone searching for his girlfriend Ashley (Gina Holden) and fearing for her life. As the city crumbles and the convicts start to take survivors hostage, the Air Force bombers are called. Led by LT. Grisham (Christopher Judge) the clock is ticking to save as many lives as they can, rescue the hostages and for Calvin and Ashley to re-unite before L.A. collapses into rubble and flames.
