US undersea lab vanishes . . .

At the same time, off Bermuda, a bathysphere operated by NUMA and overseen by Kurt Austin is attacked and becomes stranded half a mile below the surface. Only quick thinking and bold action will save the crew - which includes the head of a certain, now-missing undersea lab - from a watery grave.

Now Austin must put his life on the line in order that millions will be saved from death . . .
