If a single saci performs many pranks, imagine if all of them were to meet? This is what ends up happening. In addition to Saci-Pererê, several sacis attend the meeting: Saci-Ave, Saci-Avisador, Saci-Cererê, Saci-Trique and many others. But this time they have a serious issue to deal with: how can they keep humans afraid of them, so that they do not forget these naughty beings? Cunning characters such as Pedro Malasartes, Romãozinho, Vira-Ropa, also behave mischieveously in this book.
