Guns vs Nuns.

A catholic nun from the 13th century is teleported into the trenches of World War I during a deadly assault. Upon seeing the horrors of modern war, the nun decides to bring the gift of forgiveness and kindness to the soldiers at the front. To achieve her goal, she has to use her special ability of slowing the time down within a small area; Platforming over the bullets frozen in time, she has to reach every soldier and pray with them to stop the killing on the western front and ultimately end one of the bloodiest wars in human history.
The soundtrack would be mainly hardcore japanese techno, though within the time freeze bubbles you would hear remixes of Mozarts Für Elise.
