A Great Darkness is
spreading over E-Space. Entropy increases. In search of a last exit to
anywhere, the TARDIS arrives on the power-less planet of Apollyon, where the
scientist Pallister guards the only way out – a mysterious portal. But the
portal needs power to open, and the only power Pallister can draw on is the
energy contained within the molecular bonds of all living tissue...
The Doctor, Nyssa, Tegan and Turlough soon learn that neither Pallister nor his ally, the space pirate Captain Branarack, will stop at murder to ensure their escape. But they're not the only menace on Apollyon. The Sandmen are coming – creatures that live on the life force; that live on death.
Death is the only way out into N-Space. Death, or sacrifice.
But whose death?
Whose sacrifice?
