At Corkscrew Swamp Sanctuary, burn boss Mike Knight uses fire to preserve ancient habitats in the area, including the last remaining stands of old growth bald cypress. Before his entire team arrives, Mike scouts the location of where the fire will be started. He is joined by Evan, an intern who has a passion for restoring nature. Mike shows Evan around the site. He explains how these environments need fire to thrive and also warns him of some of the dangers of setting off a controlled burn. The rest of the crew arrives and they start lighting up sections of the sanctuary. Mike explains that, as much as they try to control the direction of the burn, nature ultimately decides.
