Fire. The light by which we tell our stories and mythic tales. It kept the night at bay for hundreds of thousands of years. It guided humanity's migrations across the globe, and became mankind's first weapon of mass destruction. What if fire developed a mind of its own? Firefighting is already a tough job even in 2026. Captain Duane "Longhand" Longhurst and probationary firefight Malcolm O'Connell of Salt Lake City's Station 8 discover it's going to get much harder. A phenomenon of particle physics called Self-Propagating Organized Thermotroph or S.P.O.T. emerges to burn whatever they can to ingest the heat that fuels their semi-living existence. Breaking in a new enigmatic probiem, and struggling with memories of past fire calls, Captain Longhurst has to now take on the blazing entities.
