Cunk continues her journey through, around and across civilisation, taking an unproblematic look at the births of Christianity and Islam.

Cunk tells the story of the birth of two of the world's great religions and learns what came next: the fall of the Roman Empire, the Dark Ages, the Crusades, and Genghis Khan. So a bit of a rough patch for mankind, if we're honest.

Along the way, Philomena asks experts hard-hitting questions about humanity's progress, and stands on or near impressive old ruins and inside museums, before the shot cuts away to some archive of the bits that don't exist anymore or were too expensive to film at.
