Every July since 1878, two thousand of America’s wealthiest men have gathered at the Bohemian Grove near bucolic Monte Rio, California, for “the greatest men’s party on earth.” Hidden in the redwoods, protected by a vast array of federal and local police, the Bohemians feel safe from any threat.

But spying on the Bohos is great sport for the Russian River Society of Pirates and Thieves, a rowdy group of Monte Rio eccentrics. The Pirates rely on high-tech electronics, vintage technology, and old-fashioned nerve — just for fun, because they can.

And when they are co-opted by the FBI to help improve security at the Grove, they stumble across a cell of genuine terrorists in the most unlikely of places. As the suspense builds, the Pirates' true mettle is put to the test.
