Two groups decide to race to the top of each of the World Trade Center buildings on September 11, 2001. The towers are hit by terrorist attacks, but the terrorists don't die in the plane crash; they resurrect as zombies hell-bent on their mission to destroy America. As these undead jihadists continue on their path of destruction armed with box-cutters and nail-clippers, the Americans must learn to stand united in their patriotism or else face gruesome death in twin 110 story bloodbaths!
