Off the coast of Scotland lies the mysterious "Shelf," a deep-water trench whispered about in island folklore—and when Cmd. Barton's destroyer arrives for maneuvers, he dismisses Lt. Jamie Jamison's warnings about the legendary Hebrides Frog People as superstition. After depth charges anger the creatures and a captured frog man is hauled aboard, Jamison finds himself caught between his commanding officer's scientific ambitions and the desperate islanders who warn that keeping the creature will bring catastrophe. When the frog people strike back, Jamison faces an impossible choice that will test where his true loyalty lies.

A government agent, a security captain, and a dummy file converge on the truth—but by then, it may be too late to matter.
