Out on the frontier, the only friend a pony can really trust is the gun in her hoof. Out where the land is wild and the buffalo roam, more than a few ponies have foregone scratching out a living on the farms or mines to seek riches and glory on the wrong side of the law. As a particularly mysterious and valuable cargo heads west on a long train journey, six mares follow with trouble in their wake, each intending to claim the prize for her own.

Also, a lot of ponies get shot.
