Amistad
Amistad was a tale about the emancipation of a ship filled with slaves. If I am correct in remembering this, the crew of the ship was killed before the ship ported and they were forced to shore in America, where they were technically free men, until someone tried to put them up for sale. A young lawyer takes their case, and with the help of a retired President, again if I am correct, James Madison, they are freed to return to Africa. Based on a true story.
