This collection brings together the four plays that feature Ionesco's everyman protagonist Jean Berenger. In `The Killer', he comes across a "radiant city", an ideal civilization which is unfortunately being terrorized by a killer, whom he decides to track down and dissuade from committing any further crimes. In `Rhinoceros', he is the only person in a provincial town who is resisting "rhinoceritis", an affliction that turn its victims into the eponymous horned beasts. In `Exit the King', he is the powerful King Berenger the First, who refuses to acknowledge that he is dying. And in `Strolling in the Air', he acquires the capacity of flight and discovers that the celestial vault is held up by a gigantic pink pillar.
