Wildfire follows eighteen-year-old Kris Furillo (Genevieve Cortese) who, after serving time at a teen detention center, is given the opportunity to start a new life. Her talent with horses is recognized by a volunteer and local trainer (Greg Serano), who arranges a job for her at the Ritter's family run ranch. Thrown into a completely new environment, Kris must learn to deal with the challenges of fitting in, while trying not to disappoint the one family willing to give her a chance. The Ritters are facing challenges of their own even as they reach out to help Kris. Patriarch Henry Ritter (Dennis Weaver) and his daughter Jean (Nana Visitor) are in a critical stage of their battle to save the ranch from financial ruin.
