Veterinarian Darcy Jackson and her family run a small but lucrative hobby farm, raising alpacas and sheltering abused animals in Harmony Valley, a coastal ranching and agricultural community. One foggy night while Darcy is returning home after a call, she veers off the road to avoid hitting a strange creature in the road and crashes her truck. Leroy Malek and his son, Dylan have been harboring a well-kept secret for years raising and caring for hybrids. When the most powerful man in the region learns of their existence and wants to use the big cats to scare farmers and ranchers off of their land, the Maleks are forced to make a deal with the devil. Now it is up to Sheriff Hoyt Stevens and his deputy Ward Prescott with the help of Chelsea Brennan, a wildlife conservation officer to foil the plan before the valley runs red with blood.
