During her voyage on a ship to America, Norwegian immigrant Amalia Gunderson makes a solemn promise to a dying mother to watch over her five-year-old daughter, Ruth. Together, Amalia and Ruth trek to Iowa to claim the farm and former boardinghouse that Ruth has inherited, despite opposition from a difficult cousin. Struggling with an empty house and scarce resources, Amalia resolves to return the boardinghouse to its former purpose, aided by the kindness of strangers and the resilient spirit of her young charge.
As Amalia and Ruth endeavor to make ends meet, tensions rise due to a trail of orphans showing up on their doorstep. Meanwhile, Absalom Karlsson--the magistrate's son--offers legal assistance and helps them advocate for justice. With each challenge they face, Amalia and Ruth find hope in believing that with faith and determination they can overcome even the most daunting of trials.
