Zachary Quinto explores the unpredictable and terrifying phenomenon of sinkholes to determine just what causes them. He visits a Florida man whose brother was killed when their family home was literally swallowed whole by the Earth as well as a series of sinkholes that are forming a series of caves right below the houses of a quaint suburban neighbourhood.
Whether they be a part of some biblical prophecy or further evidence of mankind's effect on our planet, he's alarmed to discover that all the same, they can strike anywhere in the world, at any time.

Caesar pursued Pompey to Greece but the tide has turned and it's Caesar who is on the run. He contacts Mark Antony, who he left in charge in Rome, to come and join him with the 13th Legion but Antony seems to be in no hurry.
Vorenus has re-enlisted in Antony's Legion and he and Niobe have begun to renew their marital relationship. The presence of Niobe's sister is the only sour note in their house. Pullo meanwhile continues to train young Octavian in the use of arms and the boy's mother Atia is so pleased with his development that she decides he should take another.

Arrested and charged in 2019 with child sex trafficking, Jeffrey Epstein took his own life while behind bars in a federal prison of New York City in unclear circumstances. Many claim that Epstein had an international sex trafficking ring and he would take a lot of people down. Epstein signed a will two days before he committed suicide to move his money over to the Virgin Islands. It made it much more difficult for the victims to get restitution. Nor would the survivors see him in jail for life. But the judge was going to let some of the victims have their day in court.

As they prepare their counterattack against Caesar, Pompey's Republicans begin to squabble over both the anticipated spoils and the method of finishing Caesar off. Badly outnumbered, Caesar and Antony make their stand at Pharsalus. As they try to reach Caesar in Greece, the shipwrecked Vorenus and Pullo confront an unexpected dilemma.
Back in Rome, Atia again sends Octavia to beg protection from Servilia, who complies readily to encourage her growing friendship with Octavia. Niobe's sister Lyde comes back to see her and comforts her over Vorenus's disappearance.

In Egypt, Caesar rebukes the advisers of the boy king, Ptolemy XIII, for their presumption in eliminating Pompey and demands the man who killed him. Caesar decides to intervene in the dispute between Ptolemy and his sister-wife, Cleopatra, to ensure both Rome's grain supply and his own access to Egypt's treasure.
Antony, in an unusual show of prudence, advises against this with only half a legion in Alexandria and Cato and Scipio still at large in Africa. In Rome, Brutus gets a chilly reception from Servilia when he returns home from Greece.

The defeated Cato and Scipio fall back on the African city of Utica after the Battle of Thapsus where they decide to end it all. Caesar, after two years of fighting in Greece and Egypt, returns to Rome and receives a hero's welcome.
Meanwhile, Servilia's cold rage against the Julii clan makes Brutus's submission to Caesar even more painful. Octavian returns home from military school and Caesar, impressed with his nephew's incisive political acumen, appoints him a pontiff despite his youth.
