The story centers around the cold and rigid Abel Baragar, a self-made pioneer who has built a prosperous ranch in the Canadian West while hardening his heart against his past. Years earlier, his favorite son George married Cassy Mavor, a variety-dancer and stage singer from the frontier settlements, and left home under a dark cloud of family disapproval and financial ruin. Following George's death, Cassy returns to the homestead with her young son, hoping to find a place for the child where his father once belonged. Abel Baragar and his morose son Black Andy receive her with open hostility, determined to deny her any rights or comfort on the ranch.
Aunt Kate, the wise and resilient matriarch of the household, takes Cassy and the boy under her protection, challenging the old man's harsh doctrines and unmasking the hypocrisy of his self-righteous nature. As Cassy confronts the grim memories of the past and the lingering shadow of Lumley's tavern, where she once earned her living, the deep-seated divisions within the family begin to surface. The narrative weaves the stark realities of pioneer survival with the quiet drama of forgiveness, endurance, and human redemption against the backdrop of an arctic landscape slowly yielding to spring.
