A violent storm blows into Stingray Bay while siblings try to break the holiday boredom in their parents caravan. Suddenly, they find themselves thrust into a sub-sea mission with unexpected twists and turns. They have been hurled into the sea from the cliffs. Soon, they are struggling against the clock in a dangerous journey which they could never have imagined. This is survival of the fittest.

As an endless abyss seeks to crush them and deep-sea monsters try to make a meal of them (along with the other characters that have found themselves in this watery grave), will a daring rescue plan, hatched by the General Sabaoth, the ruler of this watery domain be able to save them? Will the kids even survive the night? What lessons will they learn on this treacheries journey?

It is up to the children to make the tough decisions and to risk everything for a stranger they neither know – nor trust. What will become of these visitors to the haunted realms of the deep?
