Matt begins with his guardian, Celia in her house. He is not allowed to leave the house because it is "too dangerous." He is five years old.
When you had your first heart attack, I poisoned Matt!
Matt is the clone of a terrible man who is well known as El Patrón. He is mistreated by everyone in the land of Opium except El Patrón, Celia, and his body guard, Tam Lin.
Are you coming?
Matt finally gets to meet his original, El Patrón and people treat him nicely, because they are afraid of El Patrón. Matt is also assigned with a body guard known as Tam Lin.
When the original dies, the copy takes his place. It means you're the new master of Opium.
El Patrón suddenly has a heart attack and needs Matt's heart to survive. However, Celia tells him that she poisoned Matt's heart so that El Patrón cannot take Matt's heart as his. This leads to El Patrón's death.
After El Patrón dies, Tam Lin helps Matt escape to the Ajo Mountains, where he can keep going and find his girlfriend, Maria, and her mother. On the way, he finds a group of orphans who are forced into hard labor and he helps them escape to San Luis.
Matt finds Maria and her mother, Esperanza who informs Matt that he is the new "Lord of Opium" since El Patrón died. Matt goes back to Opium to find out that Tam Lin was killed by the wine El Patrón wanted to serve on his 150th birthday. He then makes plans for breaking up the Opium Empire.
