Luís Cláudio is a professional boxer, champion of some tournaments, with dozens of career wins. Acelino "Popó", his younger brother, wants to follow the same path. While Luís Cláudio dedicates his time exclusively in the ring, Popó divides his day between training and work in a dedetizante, which he faces grudgingly. When the elder is invited to compete in a tournament in the United States, Popó sees an opportunity for himself.
