After a daring mission in the port city of Neapolis, Spartacus' forces double in a single day by adding a rowdy bunch of Agron's captured people. However, no one knows if the Germans are capable of loyalty and even gratitude. Meanwhile, as mass crucifixions for even uttering the mere name of Spartacus serve as a warning to any servant who would dare to conspire against the Republic, Glaber offers Gannicus the chance to pledge allegiance to Rome, determined to crush the rebellion. And now, more than ever, mighty Gannicus is at a crossroads. Will troubled Gannicus ever embrace the rebels' noble cause and follow Spartacus, the honourable leader of the damned?
