Orphaned sisters Kate and Irene are separated as children, but each keeps half of their mother's wedding ring. Years later Irene marries John West, the head of a munitions camp. Kate, as fate would have it, happens to run the saloon in the camp and she and Irene become friends, but neither has any idea that the other is her long-lost sister. Matters take a turn for the worse, however, when Kate starts a romance with Cliff, Irene's adopted brother--a relationship that Irene strongly disapproves of. Complications ensue.
