This corrido is a portrait of Raquenel Villanueva, a real defense lawyer from Monterrey who became famous in Mexico for taking on cases nobody else would touch. The song opens like an ID card: "Se apellida Villanueva y radica en Monterrey" (Her surname is Villanueva and she lives in Monterrey). Licenciada is how Mexicans address a woman with a law degree, and her nickname is "Terror de los tribunales" (Terror of the courts).
Then it turns into a courtroom argument. The judge accuses her: "Que defiendes puros narcos" (You defend nothing but drug traffickers). She doesn't flinch. "Ellos pelean el encierro, yo peleo la libertad" (They fight for locking people up, I fight for freedom) is the best line in the song, and she is blunt about money too: "paga el que puede pagar" (whoever can pay, pays), and part of it buys food for the prison. The last verses get darker: she is a single mother, "ya son muchos atentados" (there have already been many attempts on her life), and she leaves it to God to decide "a quién le toca morir" (whose turn it is to die). The video even ends with a mock radio news flash about another attack on her.
