Doctor Who: Agent of the Daleks: 1st Doctor Audio Original

On a radioactive moon on the outskirts of the Fourth Sector, the occupants of a besieged power station try desperately to hold the Daleks at bay. To this end they have apprehended a saboteur, spy, and traitor to the human race. His name is Steven Taylor. When the Doctor, Vicki and Steven first landed on the station, they little suspected the chain of events that would lead to Steven’s arrest. Now he must convince a young nurse, Chayla, and the station’s brutal Security Chief, Finn, that his intentions are honourable. But with every second wasted, the Daleks are gaining ground. With the Doctor and Vicki seemingly powerless in the TARDIS, Steven must prove once and for all that he is not an agent of the Daleks. Can anything be done to prevent the Doctor’s old enemies totally exterminating everyone on the station?
