Doctor Who - 216.01 Shadow of the Ice Warriors part one

It’s been a while since Freja was home, and after all the wonders and horrors she has seen so far in her travels, all the beautiful worlds and terrifying battles, she finds herself conflicted when the TARDIS brings her back to Denmark. Except this isn’t her home.  The Doctor and Freja are in the 10th century and find themselves caught up in a power struggle with Denmark’s ruler, Gorm the Old. With a foreign princess seeking sanctuary and the threat of rebellion growing, the travellers soon realise they can’t be sure who they can trust. And the Doctor thinks there’s a much bigger problem. Why are there Ice Warriors here? What do they want? He’s ready to stop their nefarious scheme, but how far will he go to save the day? Because if he makes the wrong call, it will be the end of his and Freja’s travels.
