The train robbery was bad. It cost Stringer thirty dollars. But when the Wild Bunch gives MacKail a .45 caliber invite to hear their side of what a nice bunch of boys they really are, it's an offer he can't refuse. After all, they're all mothers' sons, even if they would cut a man's throat for his boots. Even so, when Stringer decides to ride along, it has less to do with an exclusive than the gun pointed at his back. And when the shooing starts, MacKail's caught between the crossfire of a rabid posse and the meanest bunch of murdering, lying, cheating hombres to ever draw breath.
