Julius Caesar is attempting to fully establish his position in Rome, in which he decides to attend a party that Atia is holding in order to celebrate his victory. Meanwhile, Lucius Vorenus decides to hold his own party since he has retired from the military and is working as a civilian businessman, while Titus Pullo contemplates what he should do with all of the gold that he found, though he soon encounters Pompey's son and he takes Vorenus' advice to take him to Caesar.
An intimate drama of love and betrayal, masters and slaves, and husbands and wives, it chronicles epic times that saw the fall of a republic and the creation of an empire. The series begins in 52 BC, as Gaius Julius Caesar has completed his masterful conquest of Gaul after eight years of war, and is preparing to return to Rome. He heads home with thousands of loyal battle-hardened men, huge amounts of loot in gold and slaves, and a populist agenda for radical social change. Terrified, the aristocracy threatens to prosecute Caesar for war crimes as soon as he sets foot in Rome. Caesar's old friend and mentor, Pompey Magnus, attempts to foment mutiny in order to maintain the balance of power. Two of Caesar's soldiers, Lucius Vorenus and Titus Pullo, thwart Pompey's plan and in the process, win the eternal gratitude of Caesar and the Julian clan, affording the two plebian officers an intimate view of the ruling class. The fates of Pullo and Vorenus become entwined with those of Caesar, Mark Antony, Cleopatra and the boy Octavian, a strange and awkward child who, by political guile and bloody force, will become the first emperor of Rome.
