A Gang (Mario Maurer) is a passionate teenager with a very impulsive personality. A Gang's parents are busy with work all day and have no time to take care of their son's daily life. Therefore, A Gang, who is undisciplined, is doing nothing outside all day, either forming gangs or fighting. By chance, A Gang met a man named Song (Natcha Jantapan), who is also a rebellious teenager. Because he was dissatisfied with his mother's remarriage, he chose to run away from home. Song and A Gang are very compatible. Under A Gang's persuasion, Song joined the gang. After that, Song fell in love with the school flower Ade (Mo Monchanok Saengchaipiangpen), who is admired by everyone in the school, and caused a lot of trouble. Fortunately, A Gang is loyal, and soon he led a group of brothers to help Song.
