A lone figure stands silhouetted atop the Mausoleum of Hadrian. Behind him, the sun is setting over the centre of the known world. Far below, the river is in full flood. The City of Rome lies spread out before him on the far bank. Footsteps pound up the stairs. He's been set up. An enemy is closing in; he is cornered. He jumps.

Bruised and battered, he crawls out of the raging river. He is alone and unarmed, without money or friends, trapped in a deadly conspiracy at the heart of the Empire. The City Watch has orders to take him alive; other, more sinister, forces want him dead. As the day dies, he realises he has only 24 hours to expose the conspirators, and save the leader of the world. If the Emperor dies, chaos and violence will ensue. If the Emperor dies, every single person he loves will die.

He must run, bluff, hide and fight his way across the Seven Hills.

He must reach the Colosseum, and the Emperor.

He must make it to The Last Hour.
