The Ice Warriors return, on a sinking submarine, and it's up to The Doctor to negotiate a peace between a lone Martian and scared Russian soldiers ("Cold War"). Then, The Doctor and Clara find themselves inside a haunted house ("Hide"). Also, there's more background noise (pardon that), and the guys discuss what it was like living through the Cold War (because they're old). Please visit www.patreon.com/biggerontheinside.
