It is 1915, and young Katka Kovich leaves the only home she's ever known for a new life across the ocean. Soon she finds herself on the rough and tumble Iron Range in northern Minnesota, where she joins a community of poor immigrant workers brutally exploited by the mine bosses. When the workers strike, Katka must convince the women to risk their lives and take over the strike. Along the way, she discovers true friendship, a sense of purpose, and love. Under Ground is based on the true story of an historic mining strike and the immigrants who organized to help lead it. Katka reminds us that there are things worth dying for, but more importantly, there are things to live for.
