Track 01
Firo Prochainezo admits he did not fully know the meaning of death when he first became immortal, nor does he in the present (of 1936). He muses that he does not really know the meaning of life either, and introduces himself as a capo from the Martillo Family of the New York Camorra.

Track 02
Molsa Martillo asks Firo to go to Mexico, as Maiza Avaro presently cannot. Firo cannot believe Pietro and Dominico would have stolen Martillo (and Gandor Family) money, sentiments which Molsa shares. However, a member of the Gandors witnessed the theft; as Luck Gandor elaborates, Pietro and Dominico robbed a gambling den's profits before disappearing. Molsa thus orders Firo to hunt the two men down and reclaim the stolen money, leaving it up to Firo to decide the men's fates.

Luck volunteers to accompany Firo, and Molsa adds that they should at least teach Pietro and Dominico a lesson. Firo sighs, seemingly reluctant.

Track 03
Firo reminisces about the Pietro and Dominico he knew: Born in Mexico and best friends since they were little, they loitered on Martillo and Gandor turf as independent delinquents. Completely useless when it came to fighting and gambling, they were often teased for how good-natured they were.

He also recalls how they used to get drunk and either cry or sing over nothing, involving him whether he wanted to or not.

Track 04
While driving to Mexico, Luck and Firo discuss how hard it is to believe people as stupid and good-natured as Pietro and Dominico would commit betrayal. Firo opines that the two are so good-natured they put Isaac & Miria to shame, and Luck wonders what the latter pair are doing.

Track 05
Isaac and Miria arrive in Mexico in search of the Revolution, but are at a loss as to where to find it. They ask a nearby man for its whereabouts, and, when the man explains it ended a long time ago, Isaac wonders if a Revolution can truly end. The man finds this deeply philosophical, though Isaac objects that he is looking for men fighting rather than philosophy. Deciding that some "third-rate guerrilla failures" are a close enough substitute, the man tells them where to find the guerrilla fighters.
