Britannia, AD 44. The time has come to claim Britain for the Empire. Centurions Cato and Macro are preparing for what their leaders say will be the final battle against those natives refusing to accept the civilising force of Rome. The British savages will surely stand no chance against the might of the unstoppable Roman army.
 
But young Cato is more concerned about hot-headed cohort commander, Maximius, than about the enemy, and with Roman troops being brutally slaughtered, even grizzled veteran Macro is having doubts about the promised ease of their success. Will they be victorious - or will the battle cost both of them more than they could ever imagine?
