Belle and Adonis march into the Katakombe in pursuit of the rebel solist Tiziano, only for their mismatched band to charge straight into a trap. Belle must make unlikely allies to avoid a watery grave.

Cornered by Tiziano's army of corpses, solists from both sides join forces for survival. But how long can their ragtag band last against an enemy who's already decimated an army?

Belle has a fateful encounter in the city. Meanwhile, Adonis performs his duty as an examiner as he tried to understand what happened to Tiziano.
