Jack is hired to find Blue, the missing teen-aged daughter of his ex-wife's best friend. As he investigates, Jack discovers that there is a low-intensity war going on in the L.A's posh Palos Verdes peninsula. The Bayboys, rich teen surfers, routinely vandalize cars and terrorize outsiders to enforce a locals-only policy for surfing at their own Lunada Bay. They have also started terrorizing the Mexican day-laborers who camp in the ravines between the mansions where they work as gardeners and houseboys. Jack discovers that Blue may have been bringing them food and supplies. When one stubborn Mexican boy decides that he wants to learn to surf in Lunada Bay, the feud turns violent, drawing in arsonists, angry bikers, racist border vigilantes, and Jack's daughter Maeve, who once again puts herself at risk to help her dad.
