Poomtai works as a government secretary and he's assigned to repair an old building located not far from his office. There he finds documents, personal belongings and photographs of Jaokhun Saymamuang and his wife, Lady Pinmuang. He decides to transfer the finds to the museum, but suddenly the spirit of Pinmuang appears and stops him. She tells Poomtai the story of her life. Pin and Jaokhun fell in love with each other, and although there were difficulties on their way, they still got married. 7 years later, Pirath, Pin's childhood friend, comes back from England. They get closer again, and although Pin is now a married woman, Pirath secretly falls in love with her. Lady Sae, Jaokhun's mother, dislikes Pin and tries to match her son with Pragai, her adopted child to be Jaokhun's mistress. Jaokhun does not particularly mind, but Pin cannot accept this situation. Things get worse when Jaokhun goes on a business trip to the province, and Pragai follows him. Considering that her husband accepted Pragai as his mistress and forgot about his wife, Pin seeks confort from Pirath. However, Jaokhun mistakenly believes that his wife is cheating on him, driving her out of the house and divorcing her. The disgraced Pin returns to his mother's house and stops all communication with Pirath. Later, she dies, but her spirit, feeling guilty in front of her husband, stays in their house ready to forgive him and explain everything.
