I: Brothers

Growing up in a poor and broken home in Madrid, young Estefan Castello Alamilla was raised to be genteel and respectable. But when a 3,000€ debt drags him into the heat of the Castillian underworld, he must learn to survive, and thrive, with a vicious new set of rules that will challenge all he knows and loves. Both friends and enemies are made along the way, but in the struggle for survival, only a few will achieve supremacy.
