Plerng Prom

Twenty-five years ago, Intra (Benz Punyaporn) was abandoned by her mother, a maid in the household of Kraisorn (Montri Janeaksorn), a top national export businessman. Out of pity, Kraisorn adopted the little girl as his own daughter. This happened right after he lost his wife, who passed away giving birth to Monchaya (Kwan Usamanee)—a daughter born on the exact same day as Intra. Kraisorn hoped Intra would grow up to be a playmate for his child.
Kraisorn raised both Monchaya and Intra very well. Monchaya grew up to be a good, gentle-hearted person. In contrast, Intra became moody, self-centered, and constantly caused problems that brought shame to Kraisorn. This caused Kanlayanee (Thanaporn Rattanasen), Kraisorn's younger sister, to absolutely despise Intra to her core.
Monchaya always treats Intra with sincere kindness, but Intra believes Monchaya is just putting on an act to win everyone's love. Consumed by jealousy, Intra tries to steal Phumin (Tle Thanapol), Monchaya's boyfriend. One day, she schemes to seduce him but is flatly rejected, causing her to lose face. To make matters worse, Kraisorn appoints Monchaya to an executive position, leading Intra to mistakenly believe he is biased. The two have a fierce argument, during which Intra pushes Kraisorn down the stairs, paralyzing him from the waist down. Kanlayanee kicks Intra out of the house, claiming it was Monchaya's order, which fuels Intra's burning hatred for her sister. Despite this, Monchaya is deeply worried about Intra's disappearance. Noppadol (Tengneung Kritnakan), Kraisorn's secretary who secretly loves Intra, steps in to help search for her.
Feeling sorry for Monchaya, Phumin takes her to a temple to make merit and find peace of mind. There, they meet Nun Chan (Thanyarat Lohanan), who cryptically warns Monchaya that she is about to face a great disaster. She teaches her that "goodness and a beautiful heart are the only things that will protect you from any danger." However, Monchaya doesn't think much of it, as her mind is preoccupied with worries about Kraisorn and Intra.
Meanwhile, Intra plots to destroy Monchaya for revenge. She tricks Monchaya with a phone call, and the gullible Monchaya immediately rushes out to meet her. At the time, Noppadol is stuck in an urgent meeting, so he calls Phumin to follow Monchaya. Monchaya arrives at the designated spot near a bridge. Suddenly, Intra drives her car at high speed, violently crashing into Monchaya and sending her body flying into the water. In a twist of fate, Intra's car suffers a sudden brake failure and plunges into the river as well!
Phumin arrives just in time to witness the horrifying scene. He dives into the water, pulls Monchaya's barely breathing body out, and rushes her to the hospital. In that split second between life and death, Monchaya's soul appears before Nun Chan. Monchaya cries, believing she is dead, but Nun Chan tells her it is not her time yet—what is happening is simply destiny and the fate that she and Intra must face.
At the same time, Intra regains consciousness in the hospital. She is surprised to see Phumin closely watching over her bed and is absolutely shocked to discover she is now in Monchaya's body! Intra is deeply confused, but upon seeing Phumin's tender care and realizing that her own original body is presumed dead (as only the sunken car was found), she decides to happily remain in Monchaya's body. She is now ready to transform herself into Monchaya and claim everything that rightfully belongs to her sister.
While Intra is happily living her new life in Monchaya's body, the unexpected happens: Monchaya wakes up in a small, local hospital after villagers found her body washed ashore. Monchaya is terrified to discover that she and Intra have swapped bodies. She tries everything to prove her true identity, but no one believes her. Furthermore, her family refuses to let "Intra" return home, fearing she will harm Monchaya again.
Forced out, the body of Intra (now housing Monchaya's soul) has to rent a small house with the willing help of Noppadol. The two grow closer, and Noppadol notices a drastic change in "Intra's" behavior. The woman who once constantly insulted him is now sweet and sincere. Eventually, he believes her and learns the secret that Monchaya is trapped in Intra's body. Monchaya begs Noppadol to keep it a secret and asks him to bring Yuwadee (Fai Nichanan), Phumin's younger sister and Monchaya's best friend, to meet her. It takes a long time before Monchaya can finally convince Yuwadee of the body swap.
On the other hand, the real Intra, enjoying her life in Monchaya's body, begins to reveal her true, nasty colors. Her terrible behavior gives Phumin constant headaches, to the point where he starts doubting if he still loves "Monchaya." Meanwhile, Yuwadee and Noppadol try everything to help Monchaya return to her original body, but nothing works. Remembering Nun Chan's warning, Monchaya takes Yuwadee and Noppadol to seek the nun's guidance. However, Nun Chan reveals that nothing can fix this; they must remain in these bodies until the exact day both Monchaya and Intra turn 25 years old.
