What will happen in Bir Zamanlar İstanbul Season 1 Episode 10?

Ali has managed to catch engineer Muzaffer Tekin, the only living witness to the dark secrets of the F-16 project. While preparing to hand him over to justice, he learns that his brother Emin has been kidnapped, which changes everything. Ali and his friends take silent action to both save Emin and thwart their big plans, but Ogün also uses Emin as a bargaining chip to save himself. This complicates matters even more. Realizing that he doesn't have much in the way of catching Muzaffer Tekin, Mithat involves Çetin, but a document that suddenly comes to Çetin changes the equation. Will this document save lives or restore the balance? In the midst of all this struggle, Ali and his friends are preparing for the association they have just founded. The news that Aliya Izetbegovic, the symbol of Bosnia, is coming to Turkey pushes Ali and his friends, who want to host him in their association, to speed up the preparations. Apart from Ali, there are two other names preparing for Izetbegovic: Külhan and Mithat. Their plan is aimed at changing Turkish politics. Seher wants to distance herself from Ali because of the letter she thinks is from Ali. While Ali attributes the distance between them to his mother Serpil's words, he is unaware that the real rift is being fueled elsewhere. Will the letter and Serpil's words be enough to separate Ali and Seher, or does fate have other plans to bring them together again?
