Featured: In the west of the United States, the Sierra Nevada Mountains stretch from New Mexico to Canada. One road in particular crosses them: Interstate 80, which is one of the most dangerous in the country. The extreme weather conditions make the mountain ranges particularly difficult to navigate. In winter, blizzards and snowstorms quickly render the roads impassable. To assist with this, roadside professionals like Joey work around the clock. Another group of dedicated individuals in the region is the firefighters from Station 97. Among them are Jameson and Nathan. Situated right in the heart of the mountain range and covering an area of 1,600 km, they must be ready to respond to situations that are as perilous as they are varied. However, their missions would be impossible without the support of the California Department of Transportation.
