The power-hungry king Hyperion wants to destroy the human race and overthrow the gods. With the help of the Epirus Bow, crafted by the god of war Ares, he frees the Titans from their thousand-year imprisonment in the mountains of Tartarus. The gods are powerless to stop the mad king. The only hope for salvation lies in the hero Theseus, who embarks on an unequal war against the Titans. The gods of Olympus, led by Zeus himself, the prophetess Phaedra, and the cunning slave Stavros, join forces with Theseus in a deadly battle against the demons. Theseus must win, or the gods of Olympus will be overthrown, and Hellas will be doomed.
