Summary
The Doctor follows a psychic scream to the planet Tya, home of an Earth colony and the Tyans, a formerly advanced race which is now primitive. An archaeological expedition has uncovered the Barrier, an impenetrable shield more powerful than current force screen technology. The Doctor, with the aid of scientist Kalare, studies the symbols on the tunnel walls near the Barrier and realises that they are a mathematical formula which grants access to the interior. There, a voice requests that the Doctor bring its children to itself. The Doctor telepathically give a Tyan the completed formula, causing all members of its race to rapidly evolve into new beings.
