In Fast & Furious (2009), which drug lord is Brian O'Conner tracking?

In Fast & Furious (2009), Brian O’Conner is tracking drug lord Arturo Braga.

Brian has been reinstated as an FBI agent and is investigating Braga, whose organization recruits skilled drivers to smuggle heroin through tunnels between Mexico and the United States. Brian enters the street-racing pipeline so he can join the trafficking team, while Dominic Toretto pursues the same network after learning that its enforcer was connected to Letty Ortiz’s apparent death.

A major plot complication is Braga’s hidden identity. The man publicly presented as Braga is actually a decoy, Ramon Campos; Campos is the real drug lord operating behind the alias. Brian and Dom eventually uncover Braga’s identity, capture him in Mexico, and transport him through the tunnels toward the United States.

The film’s villains can be confused with later franchise antagonists. Carter Verone is the criminal target in 2 Fast 2 Furious, while Hernan Reyes is the antagonist of Fast Five and Dante Reyes is his son in Fast X. Mose Jakande appears in Furious 7, not this 2009 film.
