Amazing Stories - Season 1 - episode entitled "No Day At The Beach." The soldiers are all gathered after the battle has finished, discussing the bravery of one of their friends. Another soldier pulls a tarp away from the already dead body of their friend to show them he could have never performed the feats they were giving him credit for. As they stand around discussing his heroism and what they all thought they saw, you can clearly see the young "dead" soldier breathing normally.
