VJ Cac á, who works for MTV in S ? o Paulo, came to Rio de Janeiro to report on a new band whose members are very poor and live in a slum called Morro do Alem ? o. She spent a good night with one of the musicians, PQD. The next day, Cac á was attacked by two street children who wanted some money and believed that PQD was somehow involved. Under police pursuit, PQD decided to go to S ? o Paulo to visit Cac á and prove his innocence. But he met Cac á's brother Nando, who tried to persuade him to participate in a scam.
