The story of Dr. Samuel Mudd, who was imprisoned after innocently treating President Lincoln's assassin in 1865.

A few short hours after President Lincoln has been assassinated, Dr. Samuel Mudd gives medical treatment to a wounded man who shows up at his door. Mudd has no idea that the president is dead and that he is treating his murderer, John Wilkes Booth. But that doesn't save him when the army posse searching for Booth finds evidence that Booth has been to the doctor's house. Dr. Mudd is arrested for complicity and sentenced to life imprisonment, to be served in the infamous pestilence-ridden Dry Tortugas.—Alfred Jingle

On 09 April 1965, John Wilkes Booth breaks his leg after the assassination of President Abraham Lincoln. He flees with an accomplice and once in Maryland, they seek medical treatment with the country Dr. Samuel Alexander Mudd that does not know that his patient has murdered the president. Dr. Mudd is arrested by the army for helping John Wilkes Booth and together with seven other suspects, they are sent to court. Dr. Mudd is a scapegoat and sentenced to life imprisonment in the hopeless prison in the Dry Tortugas, in Gulf of Mexico. When the prison is isolated due to a yellow fever epidemic, Dr. Mudd helps the guards and the other prisoners to disease.—Claudio Carvalho, Rio de Janeiro, Brazil
