Decision time is fast approaching. Marshall Ben Corrigan is nearing retirement from a long, rewarding career as a roving law officer in the Northeast New Mexico territory circa 1886. Moving into the unknown and uncertain realm of retirement has little appeal to him. His romantic interest, widow Rachel Langford, wants him to turn in his badge and settle down with her. However, even though he finds it tempting, he still has misgivings which are not all related to leaving his life-fulfilling profession.
Compounding his uncertainty is his own survival. A routine assignment to transport a man who murdered a deputy sheriff in the town of Iron Horse Junction to the territorial capital of Santa Fe goes awry. The trials and tribulations he endures during this incident will finally cause him to make his fateful decision. Whatever he chooses—everything hangs on his ability to survive his present ordeal.
