As the wars in Gaul finally come to an end, Caesar is faced with both triumph and tribulation. On the heels of his victory comes news of his daughter's death. Awarded with the adulation of the people, he also garners the enmity of powerful opponents and former friends. In Rome, Pompey the Great must balance honor and politics as he is urged to betray an ancient rival and recent friend. Atia of the Julii tries to steer her family on the dangerous path between the growing divisions of power, and in the Gallic countryside, two unlikely allies must reclaim that which Caesar has lost.
