Abraham Lincoln vs. Zombies

During the American Civil War, rumors of a massive zombie army from the Confederacy reach Washington. The source of this threat is said to be Fort Pulaski in South Carolina, where people have sought refuge. Abraham Lincoln assembles a special team to confront the hordes of the undead under his command. However, when they reach the fortified walls of Fort Pulaski armed to the teeth, there are hardly any survivors left... but thousands of zombies. The battle against the undead becomes a fight for survival.
