Freedom Writers

The storyline of the movie takes place between 19921995, beginning with scenes from the 1992 Los Angeles Riots. Hilary Swank plays the role of Erin Gruwell, a new, excited schoolteacher who leaves the safety of her hometown, Newport Beach, to teach at Woodrow Wilson High School in Long Beach, a formerly high achieving school which has recently had an integration program put in place. Her enthusiasm is quickly challenged when she realizes that her class are all "at-risk" students, also known as "unteachables", and not the eager students she was expecting. The students segregate themselves into racial groups in the classroom, fights break out, and eventually most of the students stop turning up to class. Not only does Gruwell meet opposition from her students, but she also has a hard time with her department head, who refuses to let her teach her students with books in case they get damaged and lost, and instead tells her to focus on teaching them discipline and obedience.One night, two students, Eva (April Lee Hernández), a Hispanic girl and narrator for much of the film, and a Cambodian refugee, Sindy (Jaclyn Ngan), find themselves in the same convenience store. Another student, Grant Rice (Armand Jones) is frustrated at losing an arcade game and demands a refund from the owner. When he storms out, Eva's boyfriend attempts a drive-by shooting, wanting to kill Grant but misses, accidentally killing Sindy's boyfriend. As Eva is a witness, she must testify at court; she intends to protect her own kind in her testimony.At school, Gruwell intercepts a racist drawing of one of her students and uses it to teach them about the Holocaust. She gradually begins to earn their trust and buys them composition books to record their diaries, in which they talk about their experiences of being abused, seeing their friends die, and being evicted. Determined to reform her students, she takes two part-time jobs to pay for more books and spends more time at school, to the disappointment of her husband (Patrick Dempsey). Her students start to behave with respect and learn more. A transformation is especially visible in one of her students, Marcus (Jason Finn). She invites several Holocaust survivors to talk with her class about their experiences and takes them on a field trip to the Museum of Tolerance. Meanwhile, her unorthodox teaching methods are scorned by her colleagues and department chair Margaret Campbell (Imelda Staunton).The next year comes, and Gruwell teaches her class again for sophomore (second) year. In class, when reading The Diary of Anne Frank, they invite Miep Gies (Pat Carroll), the woman who sheltered Anne Frank from the German soldiers to talk to them. After they raise the money to bring her over, she tells them her experiences hiding Anne Frank. When Marcus tells her that she is his hero, she denies it, claiming she was merely doing the right thing. Her denial causes Eva to rethink lying during her testimony. When she testifies, she finally breaks down and tells the truth, much to some of her family members' dismay. Meanwhile, Gruwell asks her students to write their diaries in book form. She compiles the entries and names it The Freedom Writers Diary.Her husband divorces her and Margaret tells her she cannot teach her kids for their junior year. She fights this decision, eventually convincing the superintendent to allow her to teach her kids' junior and senior year. The film ends with a note that Gruwell successfully brought many of her students to graduation and college.
