The life of a young man, son of an English officer who lets himself become a prisoner of love resulting in fatalism and disgrace.

Inspired in the Play "Auto da Barca do Inferno" by Gil Vicente, the only Portuguese playwright recognized in the universal history of theater, the story of "When The Angel And The Devil Cooperate" talks about a bet: if the world ended, where would most of the humans end up? In Heaven? Or in Hell? On Earth, the Angel and the Devil come across with the story of a father, Parvo, who blames his daughter's death on Onzeneiro. While Parvo looks to get his revenge on Onzeneiro, this one tries to get rid of the murder charges by paying of the judge. They both gather with their accomplices at the same place, a brothel, without knowing about each other's presence. Here alliances are formed and broken with the help of peculiar friendships, represented by the characters of "Auto da Barca do Inferno".

Two young men from Paris bring "wonderful civilizing ideas" into the brain. But, as they returned without pity, they began to call for an auction of the furniture and objects of art that garrison their "garconiére", last vestige of the passage of opulence. The great idea would be to install a cabaret in the favela for tourists in search of new sensations and also for the inhabitants of the city. On the hill, one of the boys experiences the greatest surprise: he found there, living among the humble, teaching to read to the children, Rosinha, an enchanted little princess, queen of the hill.
