While a wildfire threatens High Meadow, an uninvited guest sows seeds of dissent. The president arrives at High Meadow with his entourage of bureaucrats and faux-military. Tillie and Angus don't have time for any distractions as a massive wildfire bears down on their settlement. It will take more than hard work and good intentions to get them through this catastrophe. Martin is leery about sending all of his men to aid those in the path of the fire thereby leaving their borders unprotected. They are most vulnerable in their commitment to help others. Wisp and Nick work the fire lines seeking out people fleeing the raging flames. Only Wisp can find those lost in the heavy smoke, risking his life to bring them to safety. Behind their backs, certain people are questioning every decision. At a time when they most need to work together, outsiders are creating divisiveness.
