In the summer of 1978, in Monroe, Wisconsin, the dead body of an elderly woman is discovered in her home. Police Chief Brandon Johns and Det. Samanthia Gates are called to investigate. The crime scene indicates that a possible murder has been committed. Birgitta Nilsen, the deceased, was a very wealthy widow who lived alone in her house. Assuming inheritance money was a likely motive for her murder, they look at the family first to establish a list of suspects. As they interview the beneficiaries of Nilsen's Will, they are confronted by a host of lies, deception, and distrust among dysfunctional family members. A third non-family beneficiary appears in the Will further complicating the investigation. As they delve deeper into the case, their increasing frustrations grow, in that none of their suspects has an alibi for the time of the murder, but, at the same time, they all had the money motive. Eventually, a possible eye witness that could identify the killer is interviewed, but the octogenarian elderly woman, who lives across the street from Nilsen, was hard of hearing, paranoid, and suffered from memory issues further hampering the investigation. Then, unexpectedly, another suspect surfaces. It was a real head scratcher for Johns and Gates as they try to unravel the mystery behind the murder. Will they get the break in the case that they need to crack it and bring the killer to justice?
