Inspector Singha, a police officer, is assigned to a chilling murder case involving seven corpses. Each victim had their eyes and mouths sewn shut with red thread before being hung from a large tree at a construction site in the city. At the crime scene, Singha meets Thup, a naïve-looking young man who happens to be the only witness. However, Thup may also be framed as the prime suspect. Thup pleads his innocence, revealing a terrifying secret: since birth, he has been able to see ghosts and the supernatural. Thup soon realizes that the vengeful spirits vanish whenever he is near Singha, whose strong fate and sacred protection from Tao Wessuwan shield him from harm. Clinging to this safety, Thup proposes moving in with Singha to help solve the mystery.
