Onur Karasu is a successful intelligence agent who has been promoted to department head at a young age and has been pursuing Civan Koral, the owner of Turkey's largest jewelry company, for some time. Civan uses Koral Jewelry as a front for his dirty dealings and is the representative of a criminal organization in Turkey. Believing that Civan is hiding documents related to his illegal activities in a safe at home, Onur starts a relationship with Civan's sister, Hilal, to gain access to the house. When he learns that Civan is planning to move abroad, Onur suddenly proposes to Hilal in order to obtain the documents before it's too late. His plan is to open the safe on the engagement day and arrest Civan, who will be there for his sister's engagement. What he doesn't account for is Hilal's close friend, Ece. Onur and Ece, as opposite as night and day, will be forced to work together in a way they never wanted.
