Ep 4. IV.

In Black Sails season 1 episode 4, titled "IV," the crew of the pirate ship Walrus continue to search for the Spanish galleon Urca de Lima, which is said to be carrying a treasure worth millions. Captain Flint and his first mate Billy Bones confront each other as tensions rise between the two. The pirate crew also faces a new threat from a rival pirate named Charles Vane, who is determined to get his hands on the treasure.

Meanwhile, John Silver, a new addition to the crew, tries to prove his worth to the others by offering his skills as a cook. However, his true motives for joining the pirate crew are put into question as suspicions arise about his loyalty.

Eleanor Guthrie, who runs the local brothel and is also involved in the pirating business, faces pressure from her father to give up her illegitimate dealings and marry a wealthy man to secure their family's future. However, Eleanor has her own plans for the future of Nassau and is determined to see them through, even if it means going against her father's wishes.

As the tension between the pirate crews and the authorities in Nassau continue to escalate, alliances are constantly shifting and betrayals becoming more common. With the Urca de Lima still out there, the pirates must do whatever it takes to find the treasure and secure their future as rulers of the seas.
