When scrappy and abrasive lawyer Kang Suk Ho is put in charge of the liquidating Byung Moon High School, he sees his own troubled past in the problematic students who live their lives with no dreams. He then offers to teach them and proclaims that he will get the five most laziest students - Hwang Baek Hyun, Gil Pul Ip, Na Hyun Jung, Hong Chan Doo, and Oh Bong Goo - accepted into Cheonha University, the most prestigious college in the country. Everyone -- including the teachers, students and the school's director Jang Ma Ri -- calls him crazy. Quirky and earnest English teacher Han Soo Jung, who believes that the purpose of education is not about getting into a good college, likewise initially objects to Suk Ho's teaching methods and motivations. But he establishes a special class for the five delinquent students, including Hwang Baek Hyun who bumps heads right away with Suk Ho, to help them prepare for Cheonha University. ~~ Based on the Japanese manga series "Dragon Zakura" by "Norifusa Mita".
