Spoiler Alert: There is one slowly-building twist that it is all but impossible not to reveal in a discussion about this book, so read on at your peril: Polly comes to learn that she's not the only fighting "man" in her squad with something to hide. Lead by novice officer Lieutenant Blouse and the far more savvy (and intimidating) Sergeant Jackrum, the recruits are hurried to the front, learning more than they wanted to along the way about the sad state of their country and the vast alliance mounting against Borogravia. Polly signs up under the alias Oliver with an infantry regiment, the Ins-and-Outs, alongside a motley handful of other recruits, including four young humans (who quickly earn the nicknames "Tonker", "Lofty", "Shufti", and "Wazzer"), Carborundum the troll, Maladict the vampire, and an Igor.

The young heroine, Polly Perks, leaves home, dresses as a boy, and joins the military to find her strong but simple brother Paul, who is the only eligible heir to the family inn and who vanished a year ago after going off to fight the Zlobenians. The setting of the story is the fantastically aggressive country of Borogravia, a constantly-at-war theocracy under the apparently mad god Nuggan, probably the only god on the Discworld to update his holy text (mostly with Abominations against things like garlic, the color blue, and babies). Monstrous Regiment, the 28th Discworld book, is one of the few late-franchise Discworld books not to center around one of the major character sets (The Watch, Death, Rincewind, or the Witches), though William de Worde from The Truth and Sam Vimes make a few appearances.
