A mismatched rehab support group spends a mandated weekend "team-building" at a rundown house in the woods. Personalities clash instantly-until a blazing firenado forms from a nearby wildfirenado barrels toward the cabin, melting everything in its path. Trapped by collapsing roads and scorching heat, the misfits must use their unusual skills-an ex-arsonist's fire knowledge, a conspiracy theorist's survival gadgets, a former gymnast's agility-to reinforce the house and outrun the spiraling firestorm when it makes its next pass. The twist: one of them secretly caused the wildfire to begin with... and the firenado feels like karma catching up.
