Kadi Det... Het Haeng Ra

Sanisa, a 20-year-old actress, lives with her younger brother Karan, who is five years younger. Burdened with all the household expenses, Sanisa works tirelessly, leaving her little time to look after Karan. Consequently, he becomes involved with drugs. When Sanisa finds out, she takes him to rehabilitation until he recovers. However, the police suddenly raid her condo and discover a quantity of narcotics. With Karan missing and the situation in chaos, Sanisa desperately tries to call her boyfriend, the actor Phiphat, for advice, but he refuses to answer.
She then decides to call an old friend, Narin. Narin is certain that Sanisa is being framed, but she is currently working as a designer in the United States and cannot return to Thailand. Instead, she contacts her older brother, Nawee, who runs a resort on the secluded Moonlight Island (Koh Saeng Chan), asking him to help without revealing the specific details of the criminal case.
Nawee is a young erotic novelist writing under the pen name "Richard Reid." His successful writing career allowed him to purchase a small, private resort on the island. At his sister's request, he secretly takes Sanisa in. However, Rachel, Nawee’s bold and fashionable partner, is far from friendly, making Sanisa feel uneasy for quite some time. Eventually, Rachel leaves for an overseas trip—but not before stealing Nawee’s latest manuscript. Misunderstanding the situation, Nawee blames Sanisa and accuses her of being the thief.
