A Brazilian police official has been sent to a remote area of the country (in the state of Goias) on some undercover mission, and along the way a beautiful female member of one of Brazil's native tribes befriends him, and at one point, saves his life. They become very close -- until they reach the policeman's destination, a diamond-mining camp, where the miners' prejudice forces the native woman into a marginal, inferior status. Once the policeman has taken care of the corrupt mining boss in a manner beyond the laws of the country, he leaves, and the woman follows him along his way out again. He knows he cannot take her back to the city with him, and not having any real respect for the native Brazilians himself, his solution to handling the problem of an unwanted female companion is not any different than his solution to handling an unwanted, corrupt mining boss.
