Twelve Titans plot to overthrow their father. Their father is Uranus, who rules the Heavens. Their mother is Gaia, who made the Earth.

With Gaia’s help, Cronus becomes King of the Titans, but an alarming prophecy leads him to imprison his own children: Hestia, Demeter, Hera, Hades and Poseidon. Only Zeus escapes. Years later, he returns to free his siblings and wage a war that will decide who rules the universe.
