Queen Nephele, once a humble fisherwoman, watches as King Athamas's obsession with his mistress Ino leads him to a monstrous act. On their daughter Princess Helle's birthday, the king abandons the child on a doomed, leaking boat, leaving her to perish in the icy depths. Consumed by shattered grief, Nephele's love curdles into vengeance. Before their daughter's memorial, she publicly exposes Athamas's cruelty and hypocrisy. Crushed by guilt and her damning truth, the king plunges into the sea in despair. Clutching Helle's conch necklace, a transformed Nephele turns her back on the past, her maternal love frozen into a final, unforgiving farewell.
