S2, E10: A soldier falls in Vietnam felled by an unusual bullet. Miraculously he survives long enough to be sent to the US for an operation. Adam Ballard the Assistant to the Secretary of Science apprises his boss of the situation. Lt. Minns survived but now has a second brainwave pattern much stronger than his own. Just like the other three. All four experience dramatic increases in intelligence over 200. And new interests: biochemistry metallurgy physics and finance. And each seem to be driven to a mysterious goal unknown even to themselves. Ballard tracks down each of them or tries to. Conover turns away from the Swedish shipyard where he was working because he seems to sense that Ballard is inside talking to his supervisor. Ballard learns that Hadley (now in South America searching for the herb rara coelensis) was working on ventilation systems. Conover had devised new alloys which were stronger and lighter than the original metals. And he finds that Renaldo has invented an anti-gravity device. I've beaten gravity he tells Ballard bitterly. He has no joy over his accomplishment. He had no choice in the matter. The unknown mission required that he do it and he did. Minns with his interest in finance is financing the whole operation. And more. He's contacting children asking them to accompany him. As Part one closes Ballard and other feds have Minns' apartment surrounded.
