Hera descends from the golden heights of Mount Olympus in modest human attire to attend the mortal nuptials of her warrior son Ares. Instead of receiving reverence, she is mistaken for his vulgar side-mistress by the bride's snobbish relatives, who shower her with insults and attempt to eject her into the mud. When she reveals her radiant divine presence, the terrified mortals collapse in groveling terror.
Returning to Olympus with wounded dignity, Hera discovers that her unfaithful husband Zeus is engaged in a scandalous affair with Medusa. Done with centuries of marital neglect and humiliation, the Queen of the Gods abandons domestic forgiveness, forging ruthless divine alliances to punish the adulterous sovereign and seize absolute dominion over the cosmos.
