Set on a Montana ranch in the mid-1800s, You Are My Sunshine tells the story of Abraham Rockhammer, his children, and his grandchildren. Abraham left Ohio with his pioneer spirit in his head and his heart. His piece of Montana did not come easy but was pristine until his new neighbor -- young Henry Weebow -- started to mine for ore on the opposite side of the sacred mountain Abraham called home. Abraham's son Jeremiah must build a family to sustain the ranch and he marries the sophisticated Elizabeth Downing, who raised her children to read, cook, and dance. These children -- Daniel, twins Maddy and Gabrielle, and Zack -- carry on despite unforeseen hardships and tragedy. The family grows in unexpected ways and their loyalty to the ranch and each other is tested to the breaking point.
