After a night of sex, Velcoro and Bezzerides recount their respective traumas-Bezzerides' childhood molestation and Velcoro's murder of his wife's supposed rapist. Semyon convinces Jordan to leave the country for Venezuela with his lieutenant Nails, where he will rendezvous with her two weeks later. He then goes to Chessani's mansion, where he finds the mayor dead, and the mayor's wife Veronica, while high, implicates his son Tony as his murderer. Meanwhile Velcoro and Bezzerides learn of Woodrugh's death and resolve to close the case. They identify Laura, Caspere's secretary, and Lenny, a photographer from the movie set of the stolen prop car, as the Osterman siblings. Visiting Lenny's home they find Laura handcuffed to the fireplace, and the bird's head mask from the earlier episodes that belongs to Lenny identifying him as the murderer of Caspere, and the man who shot Velcoro. Laura confirms that Lenny murdered Caspere, and plans to kill Holloway under the pretense of a public meeting at a train station in Anaheim to trade Caspere's tapes for money as the tapes have been erased. Bezzerides puts Laura on a bus to Seattle while Velcoro intercepts Lenny at the train station and convinces him to entrap Holloway. Velcoro takes Lenny's place, leading Holloway into a discussion of the blue diamond conspiracy with him, while Lenny sits behind them. Holloway reveals that Caspere fathered Laura illegitimately and that their mother was pregnant with Caspere's second child at the time of her murder. This revelation sends Lenny into a rage and he attacks Holloway, thereby starting a shootout between Velcoro, Bezzerides, Burris, and Lenny. Holloway shoots Lenny before both are shot by transit police as the rest make their escape amidst the confusion. Velcoro and Bezzerides meet Semyon at a secret bunker in the Black Rose bar where Velcoro convinces Bezzerides to head to Venezuela while he and Semyon plot a revenge attack on Osip. They then carry out the two-man assault on the money drop at a secret cabin, killing McCandless and Osip. On their way back, both men are ambushed-Semyon is apprehended and driven out to the desert by the cartel members who invested in the clubs he burned, while Velcoro visits his son at school in Laurel Canyon and is spotted by Vinci PD searching for him and they place a transponder on his vehicle that Velcoro spots but is unable to remove, and drives off anyway knowing his fate is sealed. Semyon cooperates with the cartel members and pays them off, but refuses to give one of the men his suit when the man demands it, as he has the last of his money liquidated into diamonds in his pocket. Semyon is stabbed and attempts to walk back to civilization, but succumbs to his wounds in the middle of the desert after a series of four hallucinations and dies. Velcoro is still being tailed by Vinci police, and bids Chad goodbye on the phone before making a last stand in the woods. Velcoro accepts his fate, confronting Burris and a tactical team who shoot him to death, mirroring the conversation he had with his father in the dream sequence from episode three. In an epilogue sequence, Tony Chessani becomes mayor of Vinci, Geldof is elected governor, the rail project goes ahead as scheduled, Velcoro is remembered as a cop killer, Gena learns from Chad's paternity test that Velcoro is 99.9% most likely his father, a newly constructed highway is named in Paul Woodrugh's memory and Woodrugh's girlfriend has given birth to his child. In Venezuela, Bezzerides is revealed to have given birth to Velcoro's second son and is living with Jordan Semyon. She meets with the journalist Velcoro assaulted in episode one, and passes all the incriminating evidence, including the Caspere case files, on to him to start a crusade against the corruption in Vinci before she, Jordan and Nails disappear in a crowd.
