Dede (Guilherne Fontes) is a Brazilian teen who lives with his middle-class grandparents who are members of the local communist party. When his grandmother dies, his grandfather's health soon fades to the point where he can't speak or walk. The local party officials ask Dede to continue to family tradition and take over his grandfather's position of social authority, but when Dede is introduced to cocaine by his best friend Alpino (Marcos Palmeira), the attraction to drugs is more appealing to him than political activism.
