"Before judging me, listen to my story." Diablo Guardián tells the unusual story of Violetta and Pig. Violetta leaves home at the age of 18, with a suitcase full of dollars, and heads to NY. There she'll be a con man, a prostitute, will flirt with drugs and lose control when she meets Nefastófeles. Meanwhile, Pig is looking for a story to tell, and Violetta will make him her Diablo Guardián.
