Having narrowly escaped death in one million AD and one million BC, Doug and Tony land in the middle of one of the bloodiest battles of the American Civil War: Gettysburg, Pennsylvania in July of 1863. Artillery fire knocks out Tony and robs him of his memory; Confederate forces find him and assume he belongs with them. Meanwhile, Union forces essentially draft Doug into their army! Both sides are looking for a large cache of gunpowder under the control of an enigmatic man named Michaels. When Doug finds out who Michaels really is, he realizes his problems have only begun!
