This play, the most "adult" of Shvarts' plays, is a political satire aimed at
totalitarianism in all forms. The plot is based on the attempt of the hero — Lancelot — to liberate people in a land suffering under Dragon's brutal rule. But his efforts meet with resistance, since most of the people have gotten used to the Dragon and considered his methods, though harsh, the only possible way; their souls become, in a way, crippled with this inability and unwilingness to resist. Says the Dragon in the play:
You see, the human soul is very resilient. Cut the body in half — and the man croaks. But tear the soul apart — and it only becomes more pliable, that's all. No, really, you couldn't pick a finer assortment of souls anywhere. Only in my town. Souls with no hands. Souls with no legs. Mute souls, deaf souls, chained souls, snitch souls, damned souls.
Lancelot killing the Dragon in a fight did not free the people; all that has changed was the Burgomaster acceding to the position formerly occupied by the Dragon, and even demanding that Elsa, the same girl who was destined to be sacrificed to the Dragon, become his wife. When Lancelot returns to the town a year later, he realizes that his task is much more complex:
This is going to be a very meticulous job... We have to kill the dragon in each one of them.
