A group of tough young Brits make their way to the west of North America, where there are numerous hazards, in the form of grizzly bears, wolves, and a few tribes of Indians who definitely did not want them there. For much of the book they are with a tribe that is very friendly, and thus we are able to learn much of the ways of these people. But towards the end of the book our heroes take part in rescuing a wagon-train of emigrants that had been attacked by a hostile tribe, and a beautiful young lady seized and ridden away with.
