Plot
On April 14, 1865, five days after the Civil War ends with Lee's surrender to Grant at Appomattox Court House, Virginia, lawyer and Union veteran Frederick Aiken, with his friends, William Thomas Hamilton and Nicholas Baker, and his wife, Sarah Weston, celebrate. Later that night, after John Wilkes Booth enters Ford’s Theater, Southerner Lewis Powell (referred to as Lewis Payne in the film) seriously wounds Secretary of State William Seward in an unsuccessful assassination attempt. German immigrant and carriage repair business owner George Atzerodt is assigned to kill Vice President Andrew Johnson, but becomes afraid, gets drunk, and runs away. Meanwhile, Booth sneaks into the President’s box and shoots his target, President Abraham Lincoln in the back of the head as he watches the play, Our American Cousin. Booth stabs diplomat and military officer Henry Rathbone, who was a guest in Lincoln's box, and leaps onto the stage, shouting, "Sic Semper Tyrannis! The South is avenged!" before escaping into Maryland. A crowd, including Aiken, Hamilton, and Baker, watches in horror as the unconscious President is taken to a nearby boarding house, where he dies early the next morning. Andrew Johnson becomes the next President.
Secretary of War Edwin Stanton orders the arrest of all suspects, including Mary Surratt. Booth and David Herold manage to evade capture for some days, but Union soldiers find a barn where they suspect the conspirators are hiding and set it on fire. Herold surrenders while Booth is shot and killed by sergeant Boston Corbett when he sees Booth raising a rifle at the other soldiers.
Maryland Senator Reverdy Johnson, Aiken's boss, is Mary Surratt's defense attorney. Her son, John Surratt, has escaped and now hundreds of agents are looking for him. Also charged are Herold, Powell, Atzerodt, Michael O'Laughlen, Edman Spangler, Samuel Mudd, and Samuel Arnold. Reverdy feels unable to defend Surratt because he is a Southerner and asks a reluctant Aiken who is a Northerner to take over the defense.
Aiken visits Mary in her cell to question her. Mary asks Aiken to look in on her daughter, Anna. Aiken does so and searches the boarding house for clues. He finds a ticket with the initials "LJW" (Louis J. Weichmann). At the court, Weichmann, a seminary friend of Mary's son John, is the first witness. He describes John's meetings with Booth, and points out Herold, Powell, and Atzerodt as frequent guests in Mary's boarding house. Aiken incriminates Weichmann by making him appear as guilty as the rest of the conspirators.
Aiken again tries to stop defending Mary because he believes that she is guilty. He meets with her intending to get evidence of her guilt when she explains that John and the others conspired to kidnap Lincoln, not to kill him. They were about to attack a carriage but were stopped by Booth, who reported that Lincoln was elsewhere. She says that John left town and went into hiding two weeks before the assassination and that she has no idea where he is. Aiken asks Anna for information to help with his trial preparations, but she refuses.
At the court, Chief Prosecutor Joseph Holt brings the innkeeper John Lloyd to the stand. Lloyd claims that Mary gave him binoculars to give to Booth and told him to prepare shooting irons and whiskey for Booth and Herold on the night of the assassination. Aiken angers Lloyd by implying that he, an admitted alcoholic, was bribed with whiskey for his testimony. Lloyd is dragged out of the courtroom after he threatens Aiken.
