The series received mixed reviews throughout its original run, however the performances of both lead actors Çağatay Ulusoy and Aras Bulut İynemli were met with critical acclaim.
The series follows the story of two brothers, Sarp (Çağatay Ulusoy) and Umut Yılmaz (Aras Bulut Iynemli), who were separated during their childhood and end up on opposite sides of the law.
Umut and Sarp's father, Metin, works as an assassin for one of the most powerful mafia leaders in Istanbul, Celal Duman (Çetin Tekindor).
They both think Umut is dead after the police bring them his blood-stained T-shirt, and Sarp grows up blaming himself for what happened to his brother and being constantly haunted by his loss.
Things take an unexpected turn when Sarp finds himself falling in love with Melek Yıldız (Bensu Soral), Celal's adopted daughter and lawyer, who, unbeknownst to him, is very close friends with his own brother.
Umut, renamed Mert Karadağ, doesn't remember anything about his family and is loyal to Celal, believing that he saved him and Melek from the abuse they had to endure on the streets.
After he falls in love with Eylem Aydın (Damla Colbay), Sarp's childhood friend, his loyalty for Celal is repeatedly tested to the point that he is starting to have doubts about his actions.
He is, in fact, working as an undercover officer for commander Yusuf Kaya in order to arrest Celal Duman, whom he blames for the imprisonment and death of his father and for the disappearance of his younger brother Umut, which deeply affected him.
Sarp has a strong sense of justice and is very intelligent and skilled, managing to gain Celal's trust and constantly avoiding being exposed as a cop.
He falls in love with Melek, Celal's daughter, and finds himself repeatedly at odds with Mert Karadağ, who is, unbeknownst to him, his long lost brother Umut.
A corrupt police officer in Yusuf Kaya's team, and initially a major antagonist, who secretly works as an informant for Celal Duman.
He falls in love with Eylem Aydın, Sarp's childhood friend, and gets close to Füsun Yılmaz, his real mother; the influence of the two women eventually makes him having serious doubts about his actions.
He has always managed to avoid prison due to the deep loyalty of his people, in spite of the multiple crimes he has committed, such as Umut's kidnapping and the murder of Melek's mother.
Celal is completely devoid of empathy, intelligent, highly manipulative and a very good liar, being capable to instill in both Umut and Melek a deep devotion towards him.
Kudret's greatest desire is to get his revenge on the man he considers responsible for ruining his life, and he constantly schemes in this direction, kidnapping even Mustafa and Melek at some point in order to torment Celal.
