The story begins in May 1915 in South Tyrol where Anderl Gruber, a son of a rich hotel owner, is attending the wedding of his sister Elisabeth (Lisl) with Italian Angelo Calzolari.

However, Fritz Weinberger, a local teacher who returns from the front and who has particularly strong hatred towards Italians, exploits this and offers Francesca to protect her identity in exchange for sexual favors.

Meanwhile, Anderl discovers Francesca's affair with Fritz and returns to the front in such a rage that he single-handedly repulses a massive attack of Italian infantry.

Initially it is planned to launch an offensive through the tunnels, but later Quinziato decides to set the explosives below the mountain to blow up the Austrian troops.

Anderl helps Angelo to return to their village, while the German and Austrian troops decide to hold the mountain despite the imminent danger.

In 2012 it was announced by Paradigm's manager David Guillod and his attorney Lev Ginsburg that William Moseley will star in a film along with Eugenia Costantini and Claudia Cardinale.
