A rescue mission leads Jay and Lila Cooper to a doomed South Sea island where nothing is as they expected. Instead of a primitive civilization, the Coopers encounter a busy colony with a mysterious leader claiming to be Adam MacKenzie, a missionary once presumed dead. To add to the confusion, someone seems to have pushed the island's self-destruct button. Earthquakes and erosion are tearing the island apart, and every moment is precious in the Coopers'...

After an argument with her father, a sullen Lila Cooper boards an Air Force flight from Japan to the U.S. Her brooding is interrupted when a sudden hijacking leads to a scuffle and an explosion, causing the plane to plummet toward the Pacific Ocean. Trapped inside a secret weapons pod on the ocean floor, Lila can do nothing but pray that rescuers will find her before her oxygen supply runs out.

Policeman Reed Shelton searches desperately for his wife, who has mysteriously vanished after the pair had been attacked by a strange being.

Fourteen-year-old Jay and his younger sister Lila accompany their father to the tiny African nation of Togwana where they experience a supernatural phenomenon through a mysterious stone.

The Coopers become involved in a murder mystery that finds them caught between the present and the past, following clues that are carved in the stone cliffs around a ghost town.
