These men are in... for the crime of their lives.

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.
