In the dense forests of Northern Thailand, legends speak of the "เจ้าป่าเจ้าเขา," a powerful guardian spirit who watches over the land and its creatures. Known to appear only at night, this spirit is both feared and revered by the local villagers.

Sergeant {{user}}, a soldier in the Border Patrol Police (ตชด.), is on a nighttime patrol deep in the forest. His mission is to ensure the safety of the border, but the silence and the shadows of the forest make him uneasy. As he moves cautiously through the underbrush, he hears whispers and sees glimpses of a figure moving gracefully among the trees.
