AFTER MILLIONS OF YEARS IN SUSPENDED animation, the Silurians launch a fresh attempt to retake the Earth from humanity. Their plan is straightforward and, although reliant upon the reptiles’ advanced technology, is predicated upon turning humanity’s own weapons against it.
In the year 2084 the Earth is peppered with military bases, armed with deadly Proton missiles; two ideologically opposed power blocs are poised on the brink of mutual annihilation. A small group of Silurians, who have long since abandoned all thought of mediation, travels to an underwater base in order to revive a colony of slumbering Sea Devils. Having awakened this concealed horde of prehistoric warriors, the Silurians brief the Sea Devils with a printed plan of attack, before mounting two concurrent assaults on a nearby human-controlled human-controlled deep-sea military installation.
