David McCallum stars as Gwyillim Griffiths, a poor but bright young man in a rural Welsh mining village who is hired to be a lab assistant to a kindly research scientist named Professor Mathers(played by Edward Mulhare). He volunteers to subject himself to a breakthrough invention that somehow can accelerate the state of human evolution thousands of years, but this gives Gwyillim increased intelligence, and physically transforms him as well, which frightens the local villagers, though his girlfriend Kathy Evans(played by Jill Haworth) remains the one person he can still connect with before it is too late... Provocative episode with fine script and makeup effects that distinguish it, along with lines like "Your ignorance makes me ill and angry."
