While on business trip in Italy with his friend Ayhan, they come across Naz, a charming pediatrician who makes an impression on both of them. Due to unforeseen circumstances Ali Nejat finds himself as a single father to his previously unknown son, Kaan. While trying to balance his life as a new father and a businessman, Ali Nejat ends up leaning on Naz for help. Naz, whom Kaan has met before, becomes important person in their lives.
