Here's the network description of the prequel:
The House of Batiatus has towered above the city of Capua for many years. “Spartacus: Gods of the Arena” will explore its deadly history before the arrival of Spartacus, and the death he carried with him.
It’s a time of transition as Quintus Lentulus Batiatus takes the reins of his father’s stable of gladiators, with ambitions to elevate the house beyond all former glories. With his beautiful, scheming wife Lucretia at his side, he will stop at nothing to see his name forever carved into history.
Batiatus stakes his fortunes on the roguish gladiator Gannicus (Dustin Clare), a man whose skill with a sword is surpassed only by his appetite to live every day as if it were his last. But there are those who would see Batiatus and his champion destroyed. Loyalties will be tested, lives shattered, and battles waged in this thrilling prequel to “Spartacus: Blood and Sand.”
