Upon his father's will, Orhan resumes the identity of "Hizir Dede" from him: an anonymous helper to those in need. (In Turkish culture, the nickname "Hizir" is someone who provides unexpected and generous help). His current protégé is Leyla, a young secretary at a firm. The owner of the firm is an honest man but is in financial difficulties. To make matters worse, he has three playboy sons who aren't the least bit interested in work, but are all sweet on Leyla. Orhan decides to take a position at the firm to straighten things up, without revealing his secret identity. This will prove to be difficult, though, since Leyla is determined to find out who her secret protector is. Moreover, the three playboy brothers see Orhan as a rival and join forces against him. Orhan now has to deal with problems in all fronts: The firm's finances, the three brothers lusting after Leyla and trying to get rid of him, and worse, his own newfound feelings for Leyla.
