The New York City Pellegrini crime family are searching for Lefty, the man that betrayed them and sent their don, Salvatore Pellegrini, to prison. They will move heaven and earth to find him. Their search will lead them to San Antonio, Texas, and an unknown family named the Guerreros.

The Guerrero family are self-proclaimed descendants of Aztec warriors. They are modern-day equalizers who exist in the shadows of the crime underworld. The Guerreros are known for assisting people who cannot take their problems to the authorities. Even law enforcement authorities have been known to seek their assistance.

Now the Guerreros have been wronged and seek revenge. To accomplish their goal, they will aid Xavier Mancini, a bastard son of the Albrizzi crime family in New York City, who has his own vendetta to achieve.

However, everyone involved with Xavier Mancini's quest is asking, Why are the Guerreros helping him? Even Xavier's stepdad, Rene Thibodeaux, a decorated New Orleans detective, knows the Guerreros must have a hidden agenda. He also knows the Pellegrini crime family and the Guerreros are on a collision course. Whatever the Guerreros' hidden agenda is, one thing is certain; Whoever wronged the Guerreros has messed with the wrong Mexicans.
