Output: Mark Thackeray Sidney Poitier, from British Guiana by way of California, took a teaching position in a London East End school in the 1967 film. He spent twenty years teaching and ten in administrative roles. He has taught the children of his former pupils, and is now retiring. Thackerays former students, Pamela Dare and Barbara Pegg Judy Geeson and Lulu reprising their roles from the original film, come to the farewell party. Thackeray announces that he is leaving for an innercity school in Chicago where he will teach again. In Chicago, he meets his former colleague Horace Weaver Daniel J. Travanti who is the principal of the school. Thackeray learns that there is an A class with good students and an H for horror class for the nogooders. He convinces the principal to let him take the H class as a history teacher. His new pupils are noisy, unruly and engaged in destructive behaviors. As he did in London, he starts by teaching them respect for others. He addresses them as Mr X or Miss Y, and expects to be called Mr. Thackeray or Sir. Little by little he learns their personal stories: Wilsie Christian Payton is a gang leader who protects his younger brother. Another is a black female who battles against double prejudice. Evie Dana Eskelson is growing up without parents and hides this to avoid being fostered. A fellow teacher, Louisa Rodriguez Saundra Santiago admires him. It is revealed that as a teenager in British Guiana, he fell in love with a Chicago girl whose father had come to build a mall. They lost contact and he went to Britain to study, became a teacher and got married. He is now a widower but decided to take this teaching opportunity to find his earlier love. At school he sets out to teach these troubled kids their true potential if they take their fates in their hands. He teaches about the nonviolent resistance of the historic fighters of civil rights. When he discovers Wilsie smuggling a gun into the school, he confronts him and convinces him to yield the gun. Mr. Thackeray delivers it to a policeman as a found object. Later, the police pressure him to reveal the identity of the gun owner because the gun had been used to kill a police officer. He refuses and has to leave the school. Evie, who has taken a job at a newspaper, decides to investigate Thackerays old love, Emily Taylor Cheryl Lynn Bruce. Evie arranges an appointment for him to meet Taylor in a hospital, where he also meets Taylors son. Thackeray learns that Taylor returned his affections, but her father kept Thackerays letters from her because she was pregnant with Thackerays son. Thackeray learns that Wilsie is hiding because he thinks that the police are after him. He convinces Wilsies brother to take him to the hiding place. Thackeray convinces Wilsie not to waste his life in violent gang life. After he confronts a rival gang looking for Wilsie, Wilsie and a friend with access to more firearms turn themselves in to the police. The pupils stage a stand in to force the principal to reinstate their beloved teacher. The term ends with a graduation ceremony and dance. Thackeray announces that he is not going back to Britain but staying in Chicago to teach the new generation.
