Overview:Caleb and Aaron are trying to escape Alexandria. Meanwhile, after intelligence reports of refugee rebels entering the city by sea, Tiberius orders the famous lighthouse extinguished, threatening the lives of many innocent fishermen too. Macky is inspired by the story of Gideon not to feel defeated by the might of the Romans. Portia, Diana and the girls make a desperate, dizzying descent from the top of the lighthouse as they take a stand against Aaron. Together they must find a way to re-illuminate the dangerous shore. Samuel’s telling of the well-known Christmas Story - where the Good News was first told to lowly shepherds - turns Caleb and Aaron from criminals into heroes.
