It was a time when a civilization that had existed for over 350 years suddenly collapsed. Trade, government, education and the rule of law ceased. This was Britain at the beginning of the fifth century. Roman legions left to fight the Emperor's wars in Europe and raiders invaded, devastated the land, burnt crops, slaughtered young and old alike and took the rest as slaves. Small groups survived, but with dwindling food supplies they faced death from starvation in the coming winter. Retired soldiers and their families found safety in an old cavalry fort after their farms have been destroyed. They took in refugees, including a village elder and a brewer and his daughter escaping from a sacked city.The soldiers want to maintain the Empire's rules until the legions return, however, the vilage elder has lost all confidence in the protection of Rome and seeks safety in a new settlement in the hills. The brewer's daughter cannot consider a future while her boyfriend remains a slave in a distant land.They all know the raiders will return. to survive, they must resolve their differences, work together and fight back against their enemies.
