[2] Norah Everhart receives a package with a picture of her husband Harry, detailing coordinates to an island east of Otaheite (Tahiti).

Harry had vanished after embarking on an expedition to find a cure for Norah's mysterious family illness, which is slowly killing her.

Moving inland, she finds a camp used by the expedition, which consisted of Harry, reporter Cassandra Ward, mechanic Frank Dayton, dermatologist Ernest De Witt, stuntman Roy Granger, and their Tahitian guide Teaharoa.

Impatient, Roy had used dynamite to blow open the well, accidentally killing himself and splatting De Witt's arm with the ichor.

The team had attempted to replicate the ritual, but abandoned it after the ship that brought them, the Lady Shannon, had washed ashore nearby.

Norah finds the expedition had set up another camp, and De Witt, now insane, had stabbed Frank, but was stopped and tied up, later disappearing.

Norah realizes the body is Cassandra's, who, coveting the sea creatures' immortality, had shot Harry, attempted the ritual, and died in the process.

Regardless of the ending, Harry is left alone, and years later, now works as the Dean of Archaeology at Miskatonic University, contemplating whether he made the right decision in lying to Norah.
