When Cella Cassidy calls Sean Knight to investigate the poisoning of a prized rodeo bronc, the veterinarian alerts his brothers Jesse and Michael. The three brothers are trying to find out who is sabotaging several of the rodeo ranches around Nevada.
Cella inherited the Triple Seven Rodeo Ranch which specializes in raising, breeding and selling rodeo bulls and horses. She had a lot riding on this particular horse. She needs to put the Triple Seven back on top. The ranch has fallen on hard times since her father's illness and Cella is now in charge. When Sean tells her the horse was poisoned, Cella thinks this is one more hurdle to overcome.
She's determined to save her father's legacy and Sean has a reputation as one of the best animal doctors in the West.
Sean and Cella try to piece together clues. Could a worker have poisoned the horse? Or did someone from the outside do this? Everything points to an inside job.
When things escalate to the breaking point, they grow more attracted to each other. And soon Sean has a new goal--to keep Cella alive.
