Mighty Zeus brings Hercules' mother, Alcmene and Hercules contributes a rescue mission to save her. Zeus' jealous wife, Hera, decides that it should now be her time. Hera occupies the Chronos Stone, source of this God's power, and unleashes the four Titans. With these behemoths on-the-loose, only the combined forces of Hercules and Xena, with Gabrielle and their trusty sidekicks Iolaus, can save Mount Olympus.
