After two weeks of watching the 3rd Doctor battling the Daleks, side-by-side with UNIT, it’s time to hurtle forward in time and watch the 10th Doctor join forces with the modern incarnation of UNIT to fight against the machinations of the Sontarans.  It’s a mega-David Tennant extravaganza this week in THE SONTARAN STRATAGEM, featuring Catherine Tate as Donna Noble meeting Freema Agyeman as Martha Jones for the first time.  Join us this week for some classic defending-the-Earth action.
