After their mother left to remarry and move abroad, three children were left in the care of their father. When he unexpectedly dies under mysterious circumstances, their aunt Nuntha steps in to look after them. Nuntha soon discovers that her brother Chai had been working undercover to collect evidence against influential criminals. Tragically, due to a grave misunderstanding, Nuntha is also killed. Despite her death, Nuntha (played by Patcharapa Chaichua) remains concerned for her nieces and nephews, and continues to watch over them as a ghost. Meanwhile, Police Colonel Sumet (portrayed by Thana Suttikamon), Chai’s commanding officer, launches an investigation into the unusual death of his agent. He is shocked to learn that the children’s caretaker is actually the ghost of their aunt Nuntha.
