This is the story of Sara (Pinkploy Paparwadee), a beautiful woman with an impressive profile, holding a degree in cosmetic science from America. She is forced to rush back to Thailand when her father, Suthee (Weerachai Hatthakowit), falls ill and requires an urgent heart transplant. Facing enormous medical bills and the tuition fees for her younger brother, Sarut (Chai Somchai), she decides to apply for a job at PD Group, a leading cosmetic company in the country. Here, she meets Pattawee Pimanadech (Mik Thongraya), the CEO of PD Group, leading to an initial misunderstanding. After Sara starts working at PD Group, she runs into A-po (Poom Kiattipoom), Pattawee’s younger brother—the person she secretly liked as a child and the one who hurt her the most.

Apo falls for Sara at first sight and actively tries to win her over. Due to the company’s precarious financial situation, their mother, Namnuan (Luknam Pamela), schemes to have Apo marry Nina (Kookkik Kochakorn), the daughter of the influential politician Rassarin (Sa Wannasa) and Prapop (Wence Falconer), hoping to salvage the company. This compels Pattawee to devise a plan to separate Sara and Apo, with Phoemboon (Giant Choenyim) as his assistant.

However, things are not as simple as planned. Apo shows no signs of backing down, and Chakriya (Mintchii Settanan), A-po’s close friend who has long harbored feelings for Pattawee, tries to sabotage Pattawee’s plans. The complications don't end there. Chakrit (Big Krissada), Chakriya's only older brother, who holds a grudge against the Pimanadech family, also gets involved. Chakrit attempts everything to seize control of PD Group, going so far as to orchestrate a scheme involving Wayo (Sun Kongpop), Pattawee’s youngest brother, which spirals the situation further out of control.

What began as a deliberately staged plot for love intended to save the company transforms into a plan that will change all of their lives forever. Will they be able to overcome the tumultuous events that unfold? Follow the excitement in the drama, "BEAUTY REBORN."
