Atlantis: The Last Days of Kaptara

Crushed by the armies of Kaptara, the city of Athens is forced to hand over its children in sacrifice to a bloodthirsty god. Only the crown prince Theseus dares stand against the empire. He must venture into the depths of a mysterious temple to face a monstrosity more terrifying than anything civilized man has ever seen. KAPTARA is a retelling of the Greek Myth of Theseus, prince of Athens, and his epic battle with the Minotaur, a flesh-eating monster with the body of a man and the head of a bull. It is a unique blend of history, horror, and Bronze Age science fiction. - IMDb
