The Seven Madmen is set in Buenos Aires in the then-present-time of 1929 and opens with main character, Remo Erdosain, a self-described "hollow man, a shell moved simply by the force of habit" being accused of embezzling by his employer. That accusation sets loose a chain of events in his life, which ultimately lead him to a gathering of other discontents that make ruthless, detailed plans to set up a "bandit aristocracy." Erdosain is an anguished, pained man whose diatribes portray him as one of the madmen of the title. Nothing goes right for him: his wife, Elsa, leaves him for another man and he?s a failed inventor. Darkness pervades his very being. In The Seven Madmen Erdosain is surrounded by various other characters, richly described by Arlt: Ergueta the pharmacist, a gambler with a religious side and his wife, Hipolita, a former prostitute; Gregorio Barsut, Elsa's cousin, a boorish moneyed man who's the focus of the madmen's kidnap plot.
The madmen, headed by one called the Astrologer, believe it is "magnificent lies" that drive people on. As explained to Erdosain: "Men only respond to lies. (The Astrologer) gives lies the consistency of truth; people who never have so much as budged to get anything, guys who have become totally cynical and desperate, come to life again in the truth of his lies." What happens to Erdosain and his cohorts is continued in Arlt's third novel, The Flamethrowers (Los Lanzallamas), which followed in 1931.
