Fire and plant life have been tangled together since the first forests appeared, and this film traces that relationship from the earliest wildfires in the geological record to the present surge in what scientists now call megafires. It treats fire not as an occasional disaster but as a force that shaped the evolution of land plants themselves, some species adapting bark, seeds, and root systems specifically to survive or even depend on burning. The film then turns to the present, where fires are growing larger, hotter, and harder to contain, and asks what has changed: fuel loads, drought, land management, a warming climate, or some combination of all four. Scientists and researchers walk through burned landscapes and lay out the evidence linking ancient fire ecology to today's crises. Rather than treating megafires as an unprecedented anomaly, the film places them inside a much longer timeline stretching back hundreds of millions of years, making the case that understanding fire's deep history is necessary to understanding why it is intensifying now.
