Blood and Hope (Doctor Who)

The Civil War-a time of great unrest, when fathers found themselves in conflict with their sons and when lawlessness and slavery was rife. The Doctor, together with his companions Peri and Erimem, arrive in the middle of the conflict. The Doctor manages to cope in his own inimitable manner, however Peri - an American - and Erimem - a dark-skinned Egyptian - find themselves faced with all the bigotry and haired that typified the war for some.
