In this new adventure, Maluquinho is spending the holidays at the home of his grandfather Tônico (Stênio Garcia), an inventor who lives in a small community in the interior of Minas Gerais. His friends Junim (Samuel Brandão), Lucio (Cauã Bernard Souza), Bocão (João Romeu Filho) and Nina (Fernanda Guimarães) are coming to the city to help Maluquinho organize the circus for the centenary of the city. On this trip, they meet Tatá-Mirim, a small flame that ends up making the city believe that they are being invaded by the Capeta. So they end up living many adventures.
