The feminine spirit of the West comes alive in early twentieth century Montana. Set in the Copper Camp of Butte, Montana in 1917, Copper Sky tells the story of two women with opposite lives. Kaly Shane, mired in prostitution, struggles to find a safe home for her unborn child, while Marika Lailich, a Slavic immigrant, dodges a pre-arranged marriage to become a doctor. As their paths cross, and they become unlikely friends, neither knows the family secret that ties them together.
