Sanem is a young woman who aspires to be a writer and live on the Galápagos Islands. Despite working at her father's grocery store, she is forced by her parents to choose between an arranged marriage with her neighbor Muzaffer and finding a suitable job. Sanem lands a job at Fikri Harika, one of Turkey's leading advertising agencies, where Leyla, her sister, is an executive assistant. The owner of the advertising agency, Azizi, has two sons, Emre and Can. Emre wants to take over the company, but his father believes Can is a better fit for the job and he is appointed manager. Can has what his father wants for the company, but he prefers to take photos in remote locations. Upon learning of his father's health problems, Can eventually agrees to run the company. Aziz also tells Can to find the spy in the company who is helping their rival, Aylin. Emre doesn't like the idea of his brother being the manager, and believes that he should have the position. Emre's plan is to make him fail, as well as becoming the spy himself. Sanem bumps into Can on a dark balcony at an opera party celebrating the company's 40th anniversary. Can thinks she is his girlfriend Polen, so he kisses her. Sanem realizes that she loves the stranger who kissed her, and gives him the codename Albatross, but hates Can, and Emre makes her believe that Can only wants to increase the value of the company so that it can be sold. Can soon falls in love with Sanem, and finds out that he kissed her that day at the opera, which begins the inevitable story of love.
