What will happen in Kötü Kan Season 1 Episode 1?

Kartal is a former police officer who works as the security manager of a nightclub. One night, when an underage girl dies in the club, he is confronted with the fact that things are not as they seem and he goes after this dark web that he will never be a part of. The same night, he receives news of the death of his mother-in-law who was looking after his two children. Aside from the excitement of finally being reunited with his children from whom he has been estranged for years, he is a little nervous about coming face to face with his children who blame Kartal for their mother's death. While Kartal is tracking the causes of the deaths in the club, he finds himself at the center of a terrible spiral of betrayal and becomes the target of Fevzi Kaya and his family, one of the most dangerous names in the illegitimate world. Fevzi Kaya's daughter Nazan is a strong woman who can stand tall in this dark world and is determined to get what her family wants from Kartal. As if that were not enough, Kartal's father, retired chief commissioner Burhan, who Kartal's star has never reconciled with, has returned and descended on the house like a judge questioning everything Kartal does, especially his paternity. As Kartal struggles to protect his children from the chaos he is drawn into, he will face difficult dilemmas that fate only deems fit for heroes.
