Lucy shows them a locket with a photo of Amy, and Connor points out that she wore it on her first trip. She tells him to change things back, but Denise says that they have to get moving before Flynn changes history. The agent says that Flynn went back to April 14, 1865, and they have to eliminate Flynn. As Lucy gets into the machine, she tells the others that Lincoln was assassinated on that date.

Lucy finds Booth's mailbox, just as Robert Todd Lincoln comes in and introduces himself as General Grant's aide. She claims that she's an actress and Robert says that he's there to return Grant's tickets because he can't make the performance that night. He sits down and says that Lincoln is coming to the play that night, and Lucy asks what it's like having Lincoln as a father. Robert admits that he's proud of his father and he's just getting started.
Nicholas says that he's going to work a piece of his old master's land, and figures that Lincoln will make him give it up. Rufus says that it won't be smooth sailing, and Nicholas realizes that he's wearing a fake uniform. Disgusted, he shoves Rufus away and figures that he's trying to get a girl by pretending to be a soldier.
The clock strikes 10 and Booth comes in. Robert recognizes him and introduces Lucy, saying that she's a new actress. The President's son talks about how Booth's brother Edwin saved him a year ago, and the Lincolns owe the Booths a great debt. Lucy then meets up with Rufus and Wyatt, and Lucy warns that they can't kill Booth without changing things too much. Rufus describes how Lincoln's death will be a disaster for blacks, and Wyatt agrees with him. Lucy insists that it's too risky, but Rufus wants to change things for the better. Before Lucy can respond, they spot Booth and follow him to the Herndon House where Booth met with his conspirators. One of them looks out the window, sees them, and opens fire with a semi-automatic weapon. Wyatt tells the others to run and provides cover fire, and is wounded. Despite that, he gets away with Lucy and Rufus.
The trio get a hotel room at the National and Rufus gets some medical supplies. Wyatt tells him how to cut out the bullet, and Lucy explains that there was a conspiracy to kill Lincoln and three other top government officials.

He invites Lucy to come as his guest, and Lucy agrees. As she goes into the station, Flynn approaches her. He says that it's war and he lost his entire family, and Rittenhouse killed them. Flynn explains that Rittenhouse is a they, not a him, and he's there to right some wrongs. The terrorist insists that he's trying to save America, and one day Lucy will help him. Lucy demands answers, but Flynn tells her not to get in her way again and walks off.
As Rufus removes the bullet, Lucy arrives and explains that Robert invited her to the play and Grant will be there. She says that she saw Flynn leave the train station, and she'll get Grant out of the balcony before Booth arrives. Lucy has bought guns, and Rufus realizes that she's going to let Booth kill Lincoln. She says that she idolized Lincoln, but if they save him then they may return to a totally different future. Wyatt asks about his wife and wonders if Lucy would use the time machine to save her. He points out that she just lost her sister and wonders if she's going to let Robert lose his father.
Flynn gives the conspirators more semi-automatic weapons, claiming that they're Prussians, and tries to give one to Booth. Booth refuses, insisting that the derringer is more dramatic and he will see it through as he imagined.
Robert arrives to get Lucy, and she hides a pistol in her purse. Wyatt and Rufus promise that they'll save Seward and Johnson, respectively, and Rufus tells her to think about who she'll save.

Nicholas draws his gun on Rufus, and the bodyguards take Atzerodt away. Impressed, Nicholas offers to buy Rufus a drink.
Lucy glances at the door, wondering where Booth is. Flynn comes in and sees her, and Lucy shouts a warning. Robert struggles with Flynn, who knocks him out and shoots Lincoln in the head. The other men attack Flynn and Lucy grabs her gun, and Flynn leaps down to the stage. He picks up his semi-automatic and runs off-stage.
Later, Lucy tells the police that they should look for Flynn. Rufus and Wyatt arrive and report that they're targets are safe, and Lucy tells them that Grant is safe. Robert comes out and tells Lucy that his father is dead. He thanks her for saving Grant, and assures her there was nothing she could do to save Lincoln.

Connor notes that the assassination was engineered by Booth and he was hunted down and killed, and Lucy under her alias saved Grant and disappeared. There's nothing about Rufus saving Johnson. Denise figures that they did their job, but Lucy worries that something may have changed because of what they altered. The agent says that they kept Flynn from destroying America and walks off.
