"The Road to War" uses elaborate and fascinating computer-generated recreations and archives never seen before to examine how the assassination of Archduke Franz Ferdinand in 1914 was used by the Austro-Hungarian Empire to start a war against Serbia. The film investigates how this regional conflict involving the Central Powers and the Triple Entente escalated to become "World War I", a war with more than 17 million dead and More than 20 million injured.

In winter, a landscape straight out of a fairy tale; in summer, still a region to refresh mind and soul – Rosegger's forest homeland. Deeply snow-covered forests, ptarmigan, snow hares, and majestic red deer in winter; refreshing streams, blossoming fruit trees, and shy fawns in spring; cooling giant trees, lush alpine meadows, and playful chamois kids in summer; otters and noble crayfish in crystal-clear trout streams, and a magnificent display of colors in autumn – all this Peter Rosegger described in his books. More than a hundred years have passed, but what has changed most since then is the people.
