During questioning by the police, a railway worker falls to his death from the multi-story police HQ. The government says it was an accident but there is a public outcry. The Superintendant and Inspector responsible are awaiting the arrival of an Investigating Judge but get more than they bargained for when a lunatic escapes and impersonates him.

The play is a farce based on events involving a real person, Giuseppe Pinelli, who fell - or was thrown - from the fourth floor window of a Milan police station in 1969. He was accused of bombing a bank (the Piazza Fontana bombing).
The events of the play itself, however, are fictional. The play opens with Inspector Bertozzo interrogating The Maniac, a histrionic character, on the first floor of the police station. The Maniac, however, constantly outsmarts the dim-witted Bertozzo and, when Bertozzo leaves the room, intercepts a phone call from Inspector Pissani. The phone call lets the Maniac know that a judge is due at the police station to investigate the interrogation and death of the anarchist. The Maniac decides to impersonate the judge, and successfully does so. He gets the police to re-enact the events, in the actual fourth floor room, and also involves a woman journalist who is trying to probe the events. The play ends with two alternative endings, one with Feletti (journalist) leaving the four policemen to be bombed and in the second, Feletti uncuffs the men who in turn handcuff her to the window frame leaving her to die. The Maniac then leaves the audience to decide what ending is best.

The impact of Marx on the 20th century was all-pervasive and worldwide, costing tens of millions of lives where Communism was imposed, resulting in brutal wars to contain or expand it, and vastly improving the lives of workers where fear of Communism resulted in social reform. This program looks at the man, at the roots of his philosophy, at the causes and explanations of his philosophical development, and at its most direct outcome: the failed Soviet Union.
