In 1862, Robert E. Lee's battle plans for the Antietam campaign fell into Union hands. Legend has it a box holding a relic which contained the source of Lee's power was found with those plans. Over time the box was hidden and the search to acquire it began. Today, the Confederate League unleashes terror and murder in a desperate hunt for the box. In the Lost Cause, Park Ranger Grayson Cole races across America to stop the Confederate League and prevent America's second Civil War.
