Instead of a Pea Soup Puking girl, a boy who has lost his musical way, and is listening to the Brazilian equivalent to Justin Bieber, is saved by a Neil Youngish priest who performs an "endocism" on him. That's the opposite of an exorcism, don't you know. He's not trying to make a bad demon leave. He's trying to make the spirit of rock and roll enter this poor musically challenged body.
I.E. Stop listening to shit and listen to RAWK.
Fun fact: This was filmed in an abandoned and filthy warehouse in the East part of Sao Paulo. No adjustments necessary to make it look this bad.
Kind of says a lot about Sao Paulo's buildings.
