In this four-story box set, Kate Stewart, Osgood and the UNIT team confront an alien invasion by the Nestene Consciousness and its army of plastic Autons.

Big Finish’s first major foray into post-2005 Doctor Who is cracking stuff. The scripts by Matt Fitton and Andrew Smith are smart and pacey, and director Ken Bentley gives it all a glossy, expensive feel. Finally, UNIT has the spin-off it deserves.
