Doctor Who 30 Day Challenge: Day 02 (re-do) - Your Favorite Classic Series Episode (Pt.3) - Frontier in Space/Planet of the Daleks

Doctor Who: Frontier in Space and Planet of the Daleks was a two serial-long story arc.  The Third Doctor and his companion Jo Grant are caught in the escalating tension between two planets, Earth and Draconia, only to discover that the Master is secretly working to provoke the two into a full-on war.  Once the Master is discovered Jo and the Doctor arrive on Spiridon encounter a group of Thals and invisible Daleks.  The Doctor must yet again fight to stop the evil Daleks to save the Thals and the Spiridon species.  I love these two serials because they just feel like perfect sci-fi stories, I love a lot of Doctor Who serials, but these two in particular just felt like perfect science fiction and not to mention they have the Master and the Daleks, just sayin.
