Class of the Titans (2005)

Cronus the King of the Titans and Zeus' father, has escaped from the Underworld at midnight of New Year's Eve. With an army of giants behind him, Cronus intends to conquer and destroy the world. Cronus escaped by aligning the planets which gave him enough power to get the party started.

While the gods of Olympus no longer have the power to stop Cronus on their own, they bring together the seven teenaged descendants of heroes from Greek mythology. Under the guidance of the gods, these chosen ones are the only ones with the power to save the world from the encroaching evil.
