In the twenty-first century, the Doctor tries to show his companions Tegan and Turlough the shape of things to come on Earth. Unfortunately, their arrival coincides with a dangerous buildup of nuclear tensions between two unspecified superpowers, and the TARDIS brings them to an underground weapons platform manned by an edgy crew – particularly crewman Maddox, who has a computer interface implanted directly in his brain to allow him to fire the sea base’s nuclear missiles with a single concentrated thought. Maddox, shell-shocked after months of unannounced battle drills, collapses, leaving the base defenseless. But the base isn’t just prone to foreign attack – the repitile Silurians and Sea Devils, both ancient races which roamed the Earth freely before the evolution and rise of man, plan to launch the base’s missiles, plunging Earth into an all-out nuclear war and destroying mankind so reptiles can once again be the masters of their world.
