A time-traveling modern woman inhabits a courtesan's body in Rama III's era. Forced into sex work, she gets caught up in a murder case with a police officer, facing unfamiliar perils.

Through a dream-like incident, Nithra travels back in time to the era of Rama III into the body of Boonta, the top girl at Mae Faeng House. This is real life, though, and Nithra has to save herself from being forced into sex work while coping with an unfamiliar time period. At the same time, she somehow gets involved with a murder case and Luang Thukkharat, or Chai, who works for the police department.—Vorachote Sakulsri
