Better the death penalty or a life sentence? During a dinner at the home of a wealthy banker, capital punishment is the main theme of the debate. A young lawyer, fresh out of college, maintains that "Living, in some ways, is better than no life at all" and with him agree most of the guests, including journalists and scientists. The banker instead believes in the contrary and offers a bet to the young man: "I would bet a million dollars [euro?] that you would not be able to remain in prison, not even for a five year period." The young man accepts, upping the sentence to 15 years and officially declares the beginning of the bet, raising the prize money to two million. Thus began, in the annex of the house of the wealthy banker, the isolation of the young man who is deprived the right to cross the threshold of the pavilion, to meet other people, to hear human voices, to receive letters and newspapers. The only activities allowed are the use of a musical instrument, reading books, writing letters, drinking wine and smoking tobacco. An experience that will forever change the young man's vision of the world and humanity. A bet that will have a totally unexpected outcome.
