Poseidon, the god of the sea, is determined to marry Amphitrite, the woman who once saved his life. He goes so far as to disrupt her wedding and carry her off by force. However, her deceitful former fiancé Delphinus colludes with foreign enemies: he not only brutally murders Amphitrite’s father, but also frames Poseidon for the crime. Overwhelmed by grief, Amphitrite stabs Poseidon—who loves her deeply—with a poisoned blade. But the moment her gravely wounded lover falls, she realizes the truth. To seek vengeance, she suppresses her sorrow and sets a trap to force Delphinus to confess his crime. In the end, she destroys the enemy with her own hands. Harboring the secret that she is carrying Poseidon’s child, she waits faithfully for her beloved to wake from his slumber.
