There are five girls named Ploy in the same class at Nusornrangsan School. They are the Active Ploy, Nerdy Ploy, Pretty Ploy, Naughty Ploy and Anon Ploy. Ploypang, an activist, is keen on participating in various club activities in the school and is trusted by teachers, so she is also ostracized by other Ploys. In the end, Ploypang fell in love with a boy named Thap, but the two broke up before graduation because of a misunderstanding.
