October 1918. Before leaving the small Northern French town of Marville, the German troops hide a large quantity of explosives, hooking up the detonator to the cathedral’s mechanical bell-striker. British army HQ dispatches Plumpick to find out where the explosives are hidden.
Plumpick finds a town deserted by all its inhabitants apart from the residents of the psychiatric hospital, who have been left behind. They’ve occupied the local buildings and made use of them as they see fit: a man who thinks he’s an army general has set up in the fire station; another, believing himself a bishop, is installed in the cathedral, while the ‘Duke of Clubs’ has taken the château, certain women have moved into the brothel, and so on.
Plumpick finds the oddness, politeness, kindness, and cheerfulness that greet him both appealing and disconcerting. When the so-called Duke of Clubs ‘recognizes’ him as being the ‘King of Hearts’, everyone is delighted and the archbishop sets about organizing the coronation.
A fantastic procession follows, which the ‘King of Hearts’ happily takes part in, despite his worries about still not having found the explosives. By chance, Coquelicot, a china doll of a girl who has been promised to the king, helps him learn how and where the detonation is set to take place.
With the explosives defused, the English troops enter the town, greeted by a terribly loud firework display. Thinking their explosives have gone off, the German troops return too. The two forces engage in a battle so fierce that there are no survivors. Seeing this, the lunatics wisely shed their clothes and return to the asylum, making sure to lock the gate behind themselves.
Plumpick receives a hero’s welcome from his countrymen, and is given a new mission: one of demolition this time. So he shows up at the psychiatric hospital, stark naked, in order to be allowed in.
