Doctor Who: The Third Doctor Adventures - The Imposters

The Doctor and the Brigadier are on the trail of stolen, advanced technology. Sarah Jane Smith is convinced an informant is leading her to a top-secret space tracking station. And Dr Elizabeth Shaw is wearing a metal helmet, covered in tin foil. 

It’s a deadly puzzle, involving a precocious schoolgirl, a Saturday night all-in wrestling star and a high-ranking military officer. There’s a plot to control the Earth’s weather and somewhere in all this, there’s a connection to the constellation of Centaurus. 

 To defeat an enemy with no regard for human life, the Doctor must battle on all fronts, but not before a lethal encounter with the Venusian karate Downward K-klak!
