Kris hopes that Flame's success in the DuPont Stakes might help Jean change her mind about Raintree's future, but Kris isn't so sure about what part, if any, play in it.
Kris is left alone in charge of Raintree when Jean goes on a trip with Charlie, Matt goes with Dani to help her look into a new racehorse, and Pablo investigates a mysterious phone call.
Universal disapproval of Kris and Junior's wedding plans has everyone on edge, and even Kris wonders if she has what it takes to be part of the Davis family.
Kris' endeavors to get accustomed to her new relationship with Matt and deal with Pablo's departure are interrupted by a surprise visit from her half brother (Ignacio Serricchio).
Kris and Junior consider a once-in-a-lifetime opportunity to relocate to Alaska for a year to work on a geothermal project in the series' penultimate episode.
The fourth season begins six months after Kris was forced out of Raintree, which has undergone significant operational changes that leave Matt pining for the past.
In the series finale, Junior's schedule goes haywire when an urgent matter in Alaska that requires his attention coincides with Kris' ride on Wildfire in the Tucker Stakes and their wedding.
