Hakan's new job begins at a party celebrating Faysal Erdem's big win with the Hagia Sophia project. Meanwhile, Zeynep follows clues to find the stone.

While Hakan visits the Princes' Islands to learn about his past, Zeynep and Kemal head to the Mausoleum of Mimar Sinan to look for the stone.

With no time to devise a better way to circumvent the museum's security system, Zeynep defers to Hakan's plan, which comes with risks.
