Who has the missing money from the 1878 Mineral Basin heist? What really happened to the missing Chance son, Patrick? Where does the search for answers to all these questions even begin? These questions propel RJ, Claire, and Sam into their next adventure. But, first, what about those Copper Q line cabins that Sam's documentary filmmaker wants to use in his film? A trek across the ranch leads to serious critter encounters for Rascal and emotional trauma for Sam and her friends. Sam's new neighbors, Dr. Scout and Mac, treat Rascal's injuries and create an immediate bond with the three friends. The trio, finally refocused on the search for the missing money, discovers the Town of Mineral Basin in mining country and decides to undertake a fishing expedition of sorts; exploring the history of mining country while researching the history of the Mineral Basin Bank Heist. Conversations in mining country add to the heist's mystery as well as its effect on the mining community. Now, two generations later, memories passed down to current residents, unanswered questions, historical archives, and old-timer stories make the trip to Mineral Basin even more haunting.

Sam needs Sheriff Charlie Ketchem's help to answer forensic questions about the new evidence while, at the same time, warning off a determined trespasser. New friend, Nacho Verde, a well-known online investigator, and reliable contractor, Ben, become central to solving the line cabin mysteries at the Copper Q. New Gila County Sheriff, Zeke Franks, becomes a part of the tight circle of friends, and together they embark on the search to solve the heist. Along the way, they encounter surprises and intrigue in their efforts to uncover the answers. Will it take all of them to uncover the truth of the heist?
