Uncanny coincidences are scattered throughout history, leading to the downfall of empires and the good fortune of everyday citizens. In this episode Tony uncovers how a deadly medieval plague was able to infiltrate a thriving Australian town in the 1900s. He ponders the destiny of a group of World War II soldiers who, by signing their names on a wall, enlisted them into a very special club. Tony reveals how a serious error of judgement nearly damned the lives of everyone in Australia's First Fleet, but that a happy accident and an unexpected visitor proved the catalysis for their salvation. And he gets an eerie sense of déjà vu when a fluke of time and place links two world wars with the same gun and the same officer. Destiny, chance and serendipity all play their part in shaping our history.
