Wealthy businessman Mehmet Demirsoy, after losing his first wife, marries a young and beautiful nurse named Elif Yilmaz. Although the couple appears to have an ideal relationship from the outside, Mehmet Demirsoy has lingering doubts about Elif Yilmaz. One night, Demirsoy receives a warning message from one of Elif's old friends that confirms his suspicions. In the message, Elif's university friend, Ipek Sahin, advises Mehmet Demirsoy to be cautious with Elif.

A short while later, Mehmet Demirsoy's young son, Baris, has a motorcycle accident and is severely injured. Although Baris survives the life-threatening situation, he is left with facial burns that require a series of cosmetic surgeries. Mehmet Demirsoy's intuition now sends warning signals about his son, who, despite appearing to have recovered, starts exhibiting unusual behavior. A nurse expresses her desire to discuss something with Mehmet Demirsoy regarding this matter, but she disappears before the conversation can take place. The chief physician claims that the nurse was transferred, but Mehmet Demirsoy believes she was murdered. The police dismiss Mehmet Demirsoy's concerns, prompting him to seek help from Kemal Guersoy, a lawyer introduced to him by a friend, to solve the case.
