A nobleman flees a corrupt court after unraveling a deadly riddle and undertakes successive sea voyages that bring exile, bereavement, and moral trial. He marries and then loses his wife in childbirth, while their daughter survives a perilous childhood marked by piracy, trafficking, and steadfast virtue. Encounters with compassionate strangers, legal danger, and acts of healing gradually lead to recognition and reunion. Presented in episodic scenes framed by a speaking Chorus, the work traces suffering and recovery, stressing providence, endurance, the testing of purity, and the eventual restoration of family bonds.
