Diamonds have been stolen at a jewelry shop in Switzerland. The Police both on the French and Switzerland side of the border deal with recovering them and dealing with the thiefs. Beautiful mountain and snow scenery.

When an SUV used for a robbery in Switzerland is discovered crushed at the bottom of a cliff in the French mountains, Officer Constance Vivier of the PGHM must once again team up with Captain Meyer of the Swiss police to find the 3 robbers on the run and their loot. But the discovery of the corpse of one of them suggests that someone else is trying to get a hold on this treasure lost in the peaks. Captain Meyer leads the investigation while trying to keep a link with his daughter Violette in rebellion against him.—Happy_Evil_Dude
