Space Security agent Marc Cory visits the planet Kembel to investigate rumours of Dalek activity in the area. However, his ship is shot down and his crewmates are poisoned by the thorns of Varga plants, genetically engineered carnivores which transform their unlucky victims into Vargas as well. Despite these dangers, Cory discovers that the Daleks have formed an alliance with several other alien species, intending to launch a war against Earth. He makes a tape of his discoveries - but is exterminated before he can get word to his superiors...
