1975 film

Two archaeologists on a scientific dig come across a vampire burial ground and discover that the creatures are about to awaken and attack a nearby village.

After the Byzantine emperor's brother, Knight Alyon, is killed, Knight Andrea swears revenge and decides to take revenge on Battal Gazi. He first kills Ahmet Turani, then raids the village where Battal lives and the banquet hall, killing people. After killing his wife and kidnapping his beloved child, Battal Gazi takes revenge on the Byzantines. Battal Gazi, who had imposed tribute on the Byzantines and inflicted heavy losses with his incredible bravery, suffers an unexpected blow. The Byzantines set a trap for Cengaver, killing his wife and kidnapping his child. By drugging his son and hypnotizing him to turn him against his father, the Byzantines aim to pit father and son against each other. The young child is raised to believe he is the son of the Byzantine Alyon and to seek revenge on Battal Gazi, whom he believes to be his father's killer. Battal Gazi, however, swears to rescue his son at any cost and to mete out the punishment the Byzantines deserve.
