Tanaka Ko, a sophomore at Tokyo Medical University, is like a college student of his time, shuttling between classes, workplaces and fraternities all day long. His life seems full, but his spiritual world feels empty. By chance, Mrs. A saw a brochure calling for the construction of a primary school in Cambodia, and his boring life seemed to change. After that, he worked together with his friends Masaji Yano (Masaishi Hashimoto), Masaji Yano (Masaoka Sakata) and Honda Chong (Matsuzaka Tauri) who met at the fraternity to build the "Pea Project". Work together to attract students from various universities to join the program. Shortly after that, four young people even flew to Cambodia for a field trip, and they were greatly impacted by the cruel living conditions there. But at this time, all kinds of tribulations hit them one after another. Can Mrs. An and others finally build a school full of hope in Cambodia? This film is based on the real experience of Ye Tianjia, a student of Medical University.
