Hell comes to Southern California every October. It rides in on searing Santa Ana winds that blast at near hurricane force, igniting voracious wildfires. Master thief Danny Cole longs for the flames. A tsunami of fire is exactly what he needs to pull off a daring crime and avenge a fallen friend.

As the most devastating firestorms in Los Angeles' history scorch the hills of Malibu, relentless arson investigator Walter Sharpe and his wild card of a new partner, Andrew Walker, a former US marshal, suspect that someone set the massive blazes intentionally, a terrifying means to an unknown end.

While the flames rage out of control, Danny pursues his brilliant scheme, unaware that Sharpe and Walker are closing in. But when they all collide in a canyon of fire, everything changes, pitting them against an unexpected enemy within an inescapable inferno.
