The dead body of a tourist is found in the mountains of Tyrol. The murder investigation focuses on the residents of a seemingly quiet village.

In 1915, the First World War is in full swing and young men are called to military service in rows - including Franz and Peter. Both are sent to the Dolomite front, in order to fend off a threatened Italian attack. Comradeship and loyalty are needed in the fight, but Franz and Peter are ever enemies. Since Peter's romance with Anna, the competition between the two flares up more. But the circumstances of the war and the harsh weather in the mountains soon end those hostilities.
