Together the three men, friends for years, vow to watch out for the women they care for. Lily and Adam are clearly falling in love and Tess has a passionate affair with Nate, a friend and Willa's lawyer. Willa struggles with her attraction to Ben McKinnon, a neighboring rancher who her father had wanted her to marry simply to join the properties. The three men in their lives stand with them, making for a stronger team. Whatever the message may be, the three sisters band together, vowing to see things through. When Adam's cat is found headless on the steps of the main house it is clear that someone is trying to send a message to the women of Mercy. Things change on the ranch when animals are found slaughtered in the mountains and then closer to the ranch. As time passes however, all of the sisters develop a grudging respect for each other. Tess does what she can to contribute while butting heads with Willa constantly. Willa has no use for either sister, and continues to run the ranch while running herself into the ground. Lily is the peacemaker, always trying to do for others and make others happy. The three sisters move into the main house and struggle in their relationships with each other.

Tess Mercy is not at all willing to give up her glamorous life in California, but does so when she realizes the fortune that is at stake. The two develop an instant attraction, one that Adam is patient to see to its fruition. Shy and nervous, Lily appreciates the beauty of the land and is immediately drawn to Adam Wolfchild, Willa's half brother. Lily Mercy, the middle child, is happy to stay, if only to escape her abusive ex-husband. Willa is devastated, not only because her life is now in the hands of two strangers, but also because it is now clear that she does not matter to her father any more than the daughters he cast aside. Willa learns at the reading of the will that unless the two sisters she has never known live on the ranch for one year the land will be given to a nature conservatory and all will be lost. Upon his death Willa steps into the role as the owner, only to find that her father has other plans.
