context: In 1987, Eastside High School in Paterson, New Jersey, is plagued with numerous problems, especially drugs and gang violence. Furthermore, the students scored poorly on the state's test of minimum basic skills.During the opening credits sequence, after a teacher is brutally beaten in the cafeteria for trying to break up a fight and the state legislature has recently passed a law proclaiming that schools that cannot meet minimum test requirements will be put in receivership, Mayor Bottman (Alan North) consults school superintendent Dr. Frank Napier (Robert Guillaume), who suggests the school hire elementary school principal Joe Louis Clark, aka "Crazy Joe" (Morgan Freeman), who was a teacher at Eastside High 20 years before, as the new principal. The mayor is reluctant at first as he knows about the trouble the radical Clark has caused in the past with his tyrant-like methods, but Clark is hired. Tension arises immediately when Clark dismisses from the school hundreds of students identified as drug dealers or abusers and troublemakers. A meeting between the parents of those students and the academic board only fans the flames as the parents side with their trouble-making kids, either refusing to believe that their kids are bad seeds or not caring about their kids actions (mostly because the parents were themselves troublemakers and bad seeds when they were in school). Clark refuses to re-admit the expelled students despite lawsuits and pressure from the parents.The next day, Clark runs into one of the expelled youths, Thomas Sams (Jermaine 'Huggy' Hopkins), who asks to be let back into the school. In a dramatic rooftop scene, Clark gives him a sharp lecture about crack and what can happen to Sams if he keeps on using it. Clark then dares Sams to commit suicide by jumping off the roof, but Sams, breaking down in tears, refuses and promises to clean up his act. Clark grants him a second chance to turn things around.However, another expelled student manages to get inside the school and attack another student before Clark comes to break up the fight. Knowing he is breaking the fire code, Clark orders all doors chained and locked during school hours to keep drug dealers out, and enlists security guards to keep the fire chief out of the school. Clark's unusual and brutal methods lead him to clash with numerous teachers and with his vice principal Joan Levias (Beverly Todd). He fires one teacher for not singing to the school anthem, and he suspends another for arguing with him in front of the students, though the suspension is reversed by the superintendent.The students take a practice version of the basic skills test, but only 33% of them pass it (the minimum passing requirement is 75%). Clark embarks on a campaign to prepare the students for the real test, culminating in a motivational assembly the morning of the exam. Over the 1987-88 school semester, the students bond with Mr. Clark, not just as a principal, but as a father figure. Clark highly values school pride, and several times throughout the film insists that all students learn the school song and be able to perform it on demand.Meanwhile, one parent whose son was expelled from Eastside by Clark, civil activist and pot user Leona Barrett (Lynne Thigpen), aligns herself with the mayor in an effort to oust Clark as part of her personal vendetta. The fire chief eventually catches Clark with chains on the doors and Barrett makes a tape recording of him ordering them removed during a surprise inspection. Clark's arrest comes after a key scene involving Kaneesha Carter (Karen Malina White), who remembers Clark from grade school. Clark is offering counsel about Kaneesha's unplanned pregnancy just before he is arrested.That night, while Clark is in jail and the mayor is preparing to remove him, the entire student body converges on the Central Office of the Paterson Board of Education in a passive demonstration. They demand that Clark be released from jail and retained as principal. Mrs. Barrett tries to convince the students that Clark has made too many wrong decisions and is not the right man to be principal of Eastside, and asks that they return to their homes before any trouble starts. The students claim that Clark cares for them and has done so much good that they will not accept anyone else as their principal, and shout down Mrs. Barrett with chants and cheers.Eventually, Clark is freed from custody to calm the crown, and to good news: enough students passed the basic skills exam, which means the current administration will retain control over the school. With that, Clark shuns both Mrs. Barrett and the mayor: "You can tell the state to go to hell!" Then Clark leads his students in singing Eastside High's school song. The closing credits feature scenes of graduating Eastside High Class of 1988 seniors, including Sams.
