The film begins eerily with the camera drooling over fossilized bodies. The stoned images, gruesome and weather-beaten, are accompanied by a quote - "In the darkness some prayed for help, others for death," attributed to Pliny the Younger". It claims it is accurate as far as the history and politics of Pompeii at that time.
Set in 79 AD,, the film dismisses the plot of the novel and invents its own set of main characters. It follows Milo (Kit Harington), a "Celta slave. He is the last surviving member of his tribe, The Horsemen."
As a young child, Milo survived the massacre by being dumped beneath the corpses while he watched his mother and his entire tribe being slaughtered by the corrupt Roman General Corvus (Kiefer Sutherland) and his Aide Proculus (Sasha Roiz).
Seventeen years later, the boy, trained to be a deadly gladiator, is the star performer at the arena in Londinium, the capital of Britanny. Soon his greedy master packs him off to the city of Pompeii to serve as violent entertainment for its blood-hungry citizens.
En route to Pompeii, by pure happenstance Milo meets and creates an impression on Cassia (Emily Browning), the non-conformist daughter of the town chief Severus (Jared Harris) and his wife Aurelia (Carrie-Anne Moss), who's heading back home after spending a rather turbulent year in Rome.
