Mookie, played by Spike Lee, is a young man navigating life in the culturally rich neighborhood of Bedford-Stuyvesant, Brooklyn. He shares a home with his sister Jade (Joie Lee) and works as a pizza delivery man for Sal's Pizzeria, owned by the Italian-American, Salvatore "Sal" Frangione, portrayed by Danny Aiello. Sal, who has run the pizzeria for a quarter of a century, struggles with his older son Pino (John Turturro), whose blatant racism causes tension in the shop. Pino's disdain for the neighborhood’s black residents clashes with the more amicable relationship Mookie shares with Sal's younger son, Vito (Richard Edson).
On an exceptionally sweltering summer day, the street corner buzzes with an array of characters, each coping with the oppressive heat in their own way. Among them is Da Mayor, an old drunk, played by Ossie Davis, who spends his days trying to win the heart of the neighborhood's matriarch, Mother-Sister, brought to life by Ruby Dee. The eclectic mix includes Radio Raheem (Bill Nunn), who is passionately devoted to blasting Public Enemy’s “Fight the Power” via his boombox, symbolizing the constant battle of “love” and “hate” with rings on his hands to illustrate their conflict.
Adding to this community tapestry, we find Smiley (Roger Guenveur Smith), a mentally disabled man who strolls through the streets, proudly displaying hand-colored images of Malcolm X and Martin Luther King, Jr. Also in the midst is Buggin' Out (Giancarlo Esposito), a young man earnestly discussing civil rights with anyone willing to listen. The local airwaves are kept lively by the charismatic Mister Señor Love Daddy (Samuel L. Jackson), who brings his unique flair to the neighborhood.
As tensions mount, Buggin' Out confronts Sal about the pizzeria's "Wall of Fame," arguing for the inclusion of black celebrities, pointing out that Sal's establishment primarily serves a black clientele. Sal firmly asserts his pride in his Italian heritage, insisting on showcasing only Italian figures on the wall. Mookie attempts to mediate this brewing conflict, suggesting Buggin' Out return after a week to allow for consideration. However, the situation escalates when Buggin' Out seeks to initiate a boycott, yet the community remains largely loyal to Sal's.
The pivotal moment strikes when Radio Raheem and Buggin' Out storm into Sal's, demanding the change of decor while blasting music at full volume. A volatile exchange culminates in Sal shattering Radio Raheem’s boombox, leading to a fierce confrontation that spills onto the streets. As the police arrive, chaos unfolds, ultimately resulting in the tragic death of Radio Raheem from a chokehold during his arrest. This incident ignites a fury among the watching crowd, and tensions boil over into a riot ignited by Mookie after he throws a trash can through Sal's window.
The mob wreaks havoc on Sal's pizzeria, and while Smiley defiantly hangs images of the civil rights leaders, the community's anger is momentarily diverted. With firefighters attempting to control the blaze and riot police clashing with the crowd, the chaos epitomizes the societal fractures at play.
The morning after the riot, Mookie faces Sal amidst the wreckage of his restaurant. The confrontation reveals a complicated relationship fractured by blame and anger, but after a heated exchange, they reach a cautious understanding. In the aftermath, as the local radio host grieves the loss of Radio Raheem, the film closes with potent quotes highlighting its thematic conflict: Dr. Martin Luther King, Jr.'s thoughts on violence and Malcolm X's perspective on the justification of self-defense leave viewers reflecting on the actions witnessed.
