191 Takamagahara (Dalek Oblivion) part five

Every harvest, bandits raid a tiny village in medieval japan. But this time it'll be different. This year the village elders have recruited a group of samurai to defend their crops. This year, they make a stand.   But with ever increasing odds, how long can the small band of samurai hold out? What's behind the strange voices a little girl can hear in her head? Who is this mysterious foreigner the Doctor, and why does he seem to know what's about to happen? As reality proves stranger than they can ever expect, the samurai soon find that there are worse things than bandits. Things that the universe thought forgotten. Things that are writing themselves back into our world. This time it'll be different.
