In the middle of the 13th century, following the death of "The Iron Sultan, Alaeddin Keykubat," Mongols attack Anatolian Seljuks to destroy the last power against "The Great Khan". Allegiance or independence turns into an issue of debate among the Seljuk statesmen. A secret resistance is possible. A new and stronger state is not a dream. Emir Celaleddin Karatay, Vizier of Seljuks is to sparkle a nationwide resistance. His way is not predictable.
Kara Murat is a dark-haired, brave and strong young raider. He is a warrior who could run into the Byzantine army just by himself and change the course of the battle fought in Serbia between Ottoman and Byzantine empires. He patrols the Ottoman borders along with the raiders and catches the attention of The Byzantine. During the battle, Kara Murat proves to be such a brave and fearless man. He would then do his best to defend his land, his people, Ottoman Empire and his family. Orhan Celebi, younger brother of Sultan Murat only aims for the throne. However, Sultan Murat leaves the throne to his son and a new era begins with Sultan Mehmet: A young, brave and believing man. The ones who think Sultan Mehmet is weak take advantage of this and they come up with evil plans.
