When Dr. Catherine Bennett is wrongfully accused of murder, she knows her fate likely lies with a noose unless she can disappear. Fleeing with a bounty on her head, she escapes with her maid to the uncharted territories of Colorado to build a new life with a new name. Although the story of the murderess in New York is common gossip, Catherine's false identity serves her well as she fills in as a temporary army doctor. But in a land unknown, so large and yet so small, a female doctor can only hide for so long.
