Wilton Preparatory College is famous for its calm and dignified teaching style and high enrollment rate. As a student in its graduating class, the ideal is to be promoted to a prestigious school. The arrival of John Keating (Robin Williams), a literature teacher in the new semester, is like a spring breeze, a departure from the seriousness of a traditional famous school. Keating takes the students in the school history building to listen to the sound of death and reflect on the meaning of life; let the boys read out their ideals on the green field; encourage students to stand on their desks and overlook the world with a new perspective. Teachers' free and divergent philosophical thinking resonates strongly in the hearts of students. They gradually learn to think and seek by themselves, bravely ask about the way of life, and even violate the access control to set up a death poetry club and sing songs in caves. Professor Keating, Mr. Keating, Captain Keating, his education is like spring breeze and rain, moisturizing things remain silently in everyone's heart.
