While Kemal and Nihan are on their way to their new lives, Emir notices Nihan's absence and goes crazy. Nihan is happier than she has ever been in her life, but Kemal predicts that Emir will follow them.

While Tarık starts working for Emir out of jealousy towards Kemal, Önder decides to do something about Emir’s threats. Zeynep gets the good news from the casting agency.
