Nearing retirement, a pragmatic Arizona sheriff, Diego Parker, in 1964 takes on one last case: the brutal murder of a prominent rancher's son. The investigation forces Diego to confront the town's open secret - an infamous brothel - and a corrupt justice system manipulated by wealth and influence. As the official case unravels, true justice is delivered through an unexpected and silent act of compassion, challenging the very meaning of the law he upheld for a lifetime.
