Elderly - uniformed - Teuton Von Baden tells colleague Winterluck a tale from his youth when he was a student in Heidelberg over fifty years earlier. A fellow student Cassan was a bully but a fine swordsman who one day challenged another youth, Macker, to a fight when he found Macker in bed with his girlfriend. Cassan chose Von Baden to be his second, giving him the perfect opportunity to do away with the over-bearing and unpopular student.
