A sea legend frames a nautical tale in which a drifting accumulation of wrecked vessels forms an ever-changing island, whispered about by sailors and absent from reliable charts. The narrative follows passengers and crew aboard a liner where a recently captured convict's presence stirs tension and reveals past crimes, while interpersonal ties among travelers and officers complicate shipboard life. Encounters with the mysterious flotilla and its hazards propel episodes of mystery and suspense, blending courtroom backstory, maritime lore, and struggles for survival as scenes shift between social interactions on deck and the dangerous, uncanny ocean setting.
