Form 4 student Fung Sun-hei of a Band 3 secondary school is a well known typical neet who is bad-tempered and performs poorly in academics. One day, Sun-hei gets in trouble for causing major havoc in school. However, headmaster Lo (Lowell Lo) gives him a final chance to redeem himself by requesting him to participate in the "Find Your Voice Trial Program" (熱血合唱團試驗計劃), a project which involves forming a classical music chorus composed of three Band 3 students who go in to nine months of special training to compete in the Intercollegiate Chorus Competition (校際合唱團比賽) afterwards. Without a choice, Sun-hei reluctantly accepts the offer. The outside world views this project as one that is more difficult than reaching to the skies and teases them as the "Rotten Orange Chorus" (爛橙合唱團). However, unexpectedly, renowned Hong Kong-American conductor Joseph Yim (Andy Lau), dubbed the "Iron-Blooded Instructor" of the music industry, who have been living seclusion for a year, returns to Hong Kong to be the conductor of the chorus.
