The story begins in Lamsonthi District, a town known for its peace, simplicity, and self-sufficient way of life. The people are kind, and the children go to school happily. However, peace is rarely everlasting, especially when modernization arrives. With progress comes both good and bad, and when something harmful like drugs starts creeping into the community, trouble follows. This marks the beginning of an unavoidable mission for five children—Manee, Mana, Piti, Chujai, and Veera—who must face the growing threat and uncover the truth behind it.
