Enlightenment Synopsis
The White Guardian warns of impending danger and directs the TARDIS to what appears to be an Edwardian sailing yacht, the SS Shadow, but is actually one of a number of spaceships taking part in a race through the solar system, the prize being Enlightenment. The yacht’s Captain Striker and his fellow officers are Eternals who feed off the thoughts and emotions of their kidnapped human crew – Ephemerals – in order to fill their own empty existences.
