Doctor Who: Shadow of the Ice Warriors part five

With both Viggo’s angry army and Ice Lord Valtarr’s deadly Ice Warriors inside the stronghold, Freja must prepare for a final confrontation against two warring adversaries. But the Doctor’s grand plan to save Denmark has one fatal flaw: with the Time Lord missing, there’s no hope. Trapped with no chance of escape, Freja, Gorm, Thyra and Princess Kasstar must face the determined aggression of the human rebellion and the wrath of the Serpent’s Eye, an Ice Warrior hit squad. Is this the end for Freja’s travels in time and space? Or could it even be the end of her life?
