Increducts make themselves be said by a man where they find themselves and discover that they are fried, an imaginary Tuscan village, in 1492. considering it first a terrible joke, they must resign themselves to the harsh reality making themselves hosting from Vitellozzo, the brother of the killed man, Remigio, who tells them of a terrible feud with such a Giuliano del Capecchio, who is exterminating his family.
