The Tribe is more than a motorcycle club – it's a family. Literally, since club leader Vince rides alongside his son Race, as well as fellow Viet Nam vet Lemmy and a passle of others. They've been together a long time, these two generations of riders. But never before have they seen the kind of trouble they're about to run up against.War is easy—lines are drawn, sides are chosen. But when the club is attacked on a lonely highway road by a trucker with unknown but quite murderous intent, their hard-scrabble existence becomes one of pure survival. And not all of 'em are going to make it through.
