An intelligent, literate western set in the closing days of the frontier
5CAV charts a five day period in the lives of two army officers; the humanitarian Lnt. Coster and the careerist Mjr. Jenness. Arranging quarters for stranded train passengers, juggling the roster for Officer of the Day, balancing family life with a workload that falls inevitably on the same small cadre of hard-pressed officers. For Coster and Jenness, this is the reality of life in winter garrison.
But with a Shoshoni chief agitating for a change of Indian Agent, a US Army Paymaster on a tour of northern posts and the arrival at Fort Glenn of two men with a shared past, the ordered routine of winter quarters is gradually disfigured by violence and tragedy – leaving Jenness pursuing a bureaucratic lynching, and Coster offering a conflicted killer a last chance of redemption.
