The Conspirator

In the wake of the assassination of President Lincoln in 1865, a country mourns its leader, and eight people are charged with conspiring to kill the President, Vice President and Secretary of State. The lone woman accused, Mary Surratt (Wright), owns the boarding house where the attack was planned. Faced with a certain death, Surratt's only hope comes in the form of a newly minted lawyer and Union war hero, Frederick Aiken (McAvoy), who reluctantly agrees to defend Surratt before a military tribunal. As the courtroom trial unfolds, Aiken realizes his client may be innocent and that she is being used as bait in order to capture the only conspirator to have escaped a massive manhunt, her son (Johnny Simmons, Scott Pilgrim Vs. The World).
