On April 14, 1865, John Wilkes Booth assassinated the 16th President of the United States, Abraham Lincoln, as part of a far-reaching conspiracy.
Director Robert Redford chronicles the aftermath of the killing in this historical courtroom drama, told from the perspective of the one woman arrested and charged for the murder.
John Wilkes Booth (Toby Kebbell) is arrested along with his co-conspirators Samuel Arnold (Jeremy Paul Tuttle), George Atzerodt (John Michael Weatherly), David Herold (Marcus Hester), Lewis Payne (Norman Reedus) and Michael O’Laughlen, as well as Mary Surratt (Robin Wright), who owned the boarding house where the men concocted their heinous plan.
Idealistic lawyer Frederick Aiken (James McAvoy) is hired to defend Surratt against the legal rhetoric of prosecutor Joseph Holt (Danny Huston).
Initially, Aiken views his client with contempt, believing her guilty. When it emerges that her son John Surratt (Johnny Simmons) is one of the alleged conspirators and he has thus far eluded capture, Aiken begins to wonder if Mary is being put on the stand just to flush her boy out of hiding.
