Januário is a con man who, with the help of his equally con-artist friends, stays at the luxurious Hotel Palácio, posing as a rich cocoa farmer in order to rob and deceive tourists.

Januário and Ananásia immediately begin dating. However, their lies about their wealth make them targets of international jewel thieves who were among the guests.
