It's the hottest day of the summer. You can do nothing, you can do something, or you can Do the Right Thing.

Salvatore "Sal" Fragione is the Italian owner of a pizzeria in Brooklyn. A neighborhood local, Buggin' Out, becomes upset when he sees that the pizzeria's Wall of Fame exhibits only Italian actors. Buggin' Out believes a pizzeria in a black neighborhood should showcase black actors, but Sal disagrees. The wall becomes a symbol of racism and hate to Buggin' Out and to other people in the neighborhood, and tensions rise.
