Barclow - an Earth-type planet on the fringes of space at an inestimably distant point in the future. Two factions have laid claim to it: humans from the nearby colony world, and a small group of Chelonian Troopers. But in nearly two hundred years of conflict not one shot has been fired in anger, there are regular socials in the trenches, and the military commanders are the best of friends.

The Doctor, Romana and K-9, arriving in the midst of these bizarre hosilities, find there's real trouble to come. A crucial election on Metralubit is looming, and K-9 is forced to begin a new career as a politician. Meanwhile, Romana meets an old friend and the Doctor discovers that a sinister hidden force may be attempting to alter the war's friendly nature.

What are the plans of Galatea, leaser of the beautiful but robotic Femroids? Who is killing soldiers on both sides of the battle lines? And will K-9's oratory save the day?

Just what is going on?

This adventure takes place between the television stories SHADA and THE LEISURE HIVE.
