Marcus is an eleven-year-old runaway slave, who with his father, are fleeing the hands of a brutal master. They shouldn't be anywhere near the bustling city of Pompeii but as it so happens, fate intervenes and the father and son find themselves right at the center of chaos when Mount Vesuvius erupts and decimates the entire city. Marcus and his father are afraid of the mountain, unlike all the residents who expect the 'great monster' to quiet down. Will they have time to escape? A fictionalized account based on true events.
