Two senior citizen sisters, Claire and Avery, must solve the murder of a bowhunter in their exotic animal sanctuary or risk spending their retirement in a hardcore Texas prison. When the police learn Claire threatened the dead hunter for trespassing, she becomes the prime suspect. Avery fears the small-town police force can't find the real killer and insists the sisters solve the murder themselves.

Despite stern warnings from the local homicide detective, Claire and Avery dig deeper into the investigation. The neighborhood rumor mongers inform them that the dead hunter is the most hated man in Rancho Exotica, and the suspect list grows longer than a homeowners' association meeting. Feeling overwhelmed, Avery enlists the aid of the community's handsome Head of Security, Jay Vidocq, who conveniently volunteers at the local police department. Avery struggles to stay focused on the investigation while grappling to ignore her growing attraction to Jay.

A page-turning ride, the sisters race to unmask the killer before he strikes again, or they end up locked behind bars.
