The story of the Invasion of Normandy on June 6, 1944, when Allied forces launched an all-or-nothing
attack on Nazi-occupied Europe via five heavily defended French beaches.

The documentary makes use of LiDAR technology to recreate the landscape; and focuses on a five-hour period on Omaha beach.
It also offers micro and macro views of the assault, detailing the experiences of individual soldiers
while also pulling back to provide a big picture of the battle.
