Set in 1964 within the primarily African-American community of the Cabrini-Green housing project in North Chicago, high school senior LeRoy "Preach" Jackson ([[Glynn Turman]](/actor/glynn-turman)) along with his best friend Richard "Cochise" Morris ([[Lawrence Hilton-Jacobs]](/actor/lawrencehilton-jacobs)) are students at Cooley High, an all-black vocational school. Their close-knit group also includes friends Pooter ([[Corin Rogers]](/actor/corin-rogers)), Willie ([[Maurice Leon Havis]](/actor/maurice-leon-havis)), and Tyrone ([[Joseph Carter Wilson]](/actor/joseph-carter-wilson)). Although Preach is an aspiring writer with a passion for poetry, he frequently skips classes, illustrating a restless spirit typical of youth.
One Friday, after a week spent avoiding school, Preach returns but barely makes it through a tedious lecture before feigning a nosebleed. He escapes with his friends to enjoy a day at the zoo, later returning too late for classes, which leads them to the neighborhood diner, Martha's. The establishment, run by the tough woman named Martha ([[Juanita McConnell]]), buzzes with laughter and music, where their classmates dance and gamble in the back. Upon arrival, they learn from classmate Dorothy ([[Lynn Caridine]]) that their history exam has been postponed to Monday, compelling the group to set aside time to study over the weekend.
While engaging in a dice game, they encounter the confident Brenda ([[Cynthia Davis]](/actor/cynthia-davis)), who demands passage through their game. Martha intervenes with a meat cleaver in hand, showcasing her role as the fierce protector of her diner. Amidst their social lives, Preach and Cochise also interact with their girlfriends, Johnny Mae ([[Jackie Taylor]]) and Sandra ([[Christine Jones]]), facing the realities of teenage relationships where Johnny Mae embraces intimacy while Sandra remains more guarded.
At home, worries of financial struggles surface as Cochise's mother, Melba ([[Lily Schine]]), hints at not receiving their welfare check while managing her boyfriend's problems. An unexpected moment occurs when Cochise finds a letter revealing a sports scholarship, heightening the boys’ spirits as they celebrate over stolen sips of wine. Their adventures lead them to a party hosted by Dorothy after a clever scheme to avoid the cover charge, showcasing a blend of youthful ingenuity and camaraderie.
Their night spirals into chaos when a confrontation arises with Damon and his possessive nature sparks a fight, setting the backdrop for further troubles. The group finds themselves in a precarious situation involving stolen cars, police chases, and ultimately landing in detention. Mr. Mason ([[Garrett Morris]](/actor/garrett-morris)), their teacher, bails them out, emphasizing their potential but warning them about their reckless choices.
As complications deepen, jealousy and misunderstandings emerge when Cochise spends time with Sandra, igniting a rift between him and Preach. Tragedy strikes when Preach tries to reconcile with Brenda while evading a gang confrontation, leading to a heart-wrenching scene when Cochise sustains fatal injuries. Preach’s desperate pleas for help highlight his emotional turmoil as he faces the stark realities of life and loss.
Cochise's funeral becomes a poignant moment, showcasing the impact he had on his friends. Preach bids farewell, promising to honor his memory while expressing his ambition to succeed. The film closes with poignant epilogues reflecting on the fates of each character, revealing the varied paths they took. Preach moved to Hollywood to chase his writing dreams, while Brenda found stability, and the fates of others serve as reminders of the harsh realities many faced, including the murder of Tyrone during the turbulent racial conflicts surrounding the 1968 Democratic convention in Chicago.
