Erin Gruwell is a new teacher assigned to teach freshman English at a difficult high school made up of underprivileged students from criminal backgrounds. She develops a new curriculum focused on having students write about their lives. She takes the students on a field trip to a Holocaust museum to learn about discrimination and compares it to what the students experience. The students become interested in Anne Frank's story. Erin helps the students understand the Holocaust and makes connections between it and racial discrimination faced by the students and groups like African Americans.
