In May 2016, a wildfire nicknamed 'the Beast' tore through Fort McMurray, Alberta, forcing 88,000 people to flee the city with almost no warning. This episode reconstructs the evacuation hour by hour: bumper-to-bumper traffic on Highway 63 as flames jump the road, residents abandoning cars, and firefighters and emergency crews trying to hold neighborhoods that keep igniting anyway. Interviews with survivors and officials trace how a routine spring fire, fed by drought and unusual wind shifts, outran every containment effort and became the costliest natural disaster in Canadian history. The film uses footage of scorched subdivisions and displaced families to show the scale of the loss, then follows the slower story of rebuilding a city that lost thousands of homes overnight. It sits within a series on extreme weather events, treating Fort McMurray as a case study in how quickly a modern city can be overwhelmed when fire behavior stops following the models emergency planners built their response around.
