Kowalski works for a car delivery service, and takes delivery of a 1970 Dodge Challenger to drive from Colorado to San Francisco. Shortly after pickup, he takes a bet to get the car there in less than 15 hours.

When a series of strange earthquakes hit California, a seismologist named Kimberly Stevenson is sent to the Angeles Forest to investigate the epicenter. This might prove to be her biggest task so far, but also the one that will bring her renown. She brings along her son, Justin, who was recently involved in a car accident with his father. In the wilderness outside Los Angeles, the two of them find a man named Michael Brandeis, who seems to know an awful lot about what is happening. As expected, these are not natural earthquakes, but the work of a dangerous company selling nuclear weapons.
