Professor James Anders is a seemingly mild-mannered teacher, an American working in Rio De Janeiro. Anders, bored with years of teaching, decides to put together a team to pull off a diamond heist during the Rio Carnival. Four international experts are brought together to carry out the robbery: a safe cracking expert, a master thief, a mechanical genius, and a playboy.

Upon learning that the school where he learned music is going to be expropriated, a famous singer decides to do a show for the benefit of the institution.
