A desperate treasure hunter must navigate the treacherous waters of the South Pacific to recover a sunken fortune before rival scavengers intervene. The protagonist, a down-on-their-luck diver, accepts a high-stakes contract to locate a shipwreck containing gold. The narrative unfolds through a text-based interface where the player must manage limited resources, navigate complex underwater environments, and solve logical puzzles to progress. The world operates on strict physical constraints, requiring the player to monitor oxygen levels and equipment integrity while contending with the unpredictable nature of the sea and the hostility of competing treasure hunters.

Discussion often centers on the high level of difficulty and the unforgiving nature of the game's resource management systems. Readers and players frequently highlight the immersive quality of the prose, which compensates for the lack of visual graphics. The pacing is noted for being deliberate, requiring careful planning and trial-and-error to successfully navigate the underwater hazards. Critics often point to the game's ability to create tension through text alone as a hallmark of the Infocom style.
