In 1970, in the Great Northern Wilderness, Su Jianye and his wife unexpectedly adopted a frail baby girl named Yaya. The couple completely cut ties with their unfairly treated original family and left with nothing, starting a new life with Yaya and their two sons. Yaya seems to be born with extraordinary good luck: she discovers precious wild ginseng, brings home abundant fishing catches, and repeatedly turns the family's fortunes around. Facing one scheme and provocation after another from their former relatives, the family supports one another and stays true to their principles. Through years of material scarcity, they work diligently together, overcome every hardship, and turn their humble everyday life into one of growing prosperity.
