Atiye revolves around the life of a young woman who has been drawing a symbol of prosperity since her childhood, without fully understanding its meaning. Atiye, played by Beren Saat, is a part-time teacher and an abstract painter. She has a relationship with Ozan, the son of a wealthy businessman named Serdar. However, Atiye finds no peace in her relationship with Ozan and continues to search for deeper fulfillment.
One day, Atiye hosts her first art exhibition, where her symbol is displayed in various colors and sizes. The exhibition receives widespread appreciation, but Atiye is intrigued by the fact that her symbol appears elsewhere besides her own artwork. Simultaneously, an archaeologist named Erhan discovers a peculiar artifact buried for thousands of years at Göbekli Tepe. Atiye realizes that the symbol she has been drawing since childhood is connected to the artifact. Determined to uncover its secrets, she decides to visit the site.
On her way to Göbekli Tepe, Atiye encounters a young girl with a star-shaped mark on her forehead and several livestock. Unable to understand the girl's language, Atiye discovers that the girl understands when she mentions Göbekli Tepe. The girl leads Atiye to the site, where she meets Erhan and shares her connection with the symbol. However, Erhan dismisses Atiye's claims, assuming the girl made up the story or lost her sanity. Despite her unsuccessful attempts to see the symbol, Atiye settles in a hotel.
To her surprise, the young girl with the star mark on her forehead visits Atiye and takes her to a cave where she witnesses the presence of purple stones. An associate of Erhan then escorts Atiye out of the area, demanding her departure. Atiye insists that a young girl with the star mark and the purple stones are still inside. The next day, Erhan and his team return to the site and find the purple stones and a painting of a girl with a star mark. Erhan reaches out to Atiye, and their destinies become intertwined with a mysterious mission against the world. Their quest is to uncover the true meaning behind their connection and the symbols they encounter. However, they soon find themselves entangled in a web of dark forces and must navigate a path fraught with danger.
