The story is basically this, a young Abe Lincoln is forced to kill his zombified Mother after his father commits suicide. Later, during the Civil War, Abe (now president) learns of a failed raid on a Southern fort where the only Union survivor to return tells tales of creatures that eat the living and whom exhibits signs of being a zombie. The survivor quickly changes into a zombie and escapes and attacks a Union officer...the Prez quickly jumps into action and taking the shortened scythe that he used to take the head off of his mother (with a folding blade no less!!) he dispatches the ghoul. Abe quickly assembles a crack team of the newly formed Secret Service (and yes in the movie they DO end up in a whore house by the way...old randy Abe apparently had a thing for hookers in the movie...) and heads to the fort to investigate. Why? I don't know....I guess he just was a take charge kind of guy like that. Once there they quickly encounter both confederate soldiers and hordes of the undead.
The rest of the movie consists of Abe and crew being whittled down by the zombies while forming alliances with each other and the confederates as well as happening upon an old flame of Abe's and ends up with Stonewall Jackson of all people saving the day (with a ridiculously unauthentic hat on) blowing up the zeds and a rather unexpected twist. All in all a fun flick to watch if you don't take it TOO seriously.
Here is a review by a guy who I think did take it a bit too seriously being that he reviews B movies to begin with, but had some kind words to say along the way as well....
Again, its on Netflix for those of you that are still subscribing to it.. Enjoy. (BTW, if you search the title on YouTube you might find a surprise....)
