Nan Lorimer promises her dying mother that she will protect her younger sister Masie, but the latter nonetheless falls prey to the unscrupulous Dr. Thornton and secretly meets him. One evening, Masie is rescued from a New York subway disaster by wealthy miner John Harwood, who courts and marries her. Although John deeply loves Masie, he neglects her for his work, and she eventually renews her friendship with Thornton, agreeing to visit his apartment. Thornton is attacking Masie when Nan arrives to save her, but just then John appears and demands to see his wife. To salvage Masie's marriage, Nan claims to be Thornton's sweetheart, whereupon John quietly departs. Nan's fiancé Allen, having overheard everything, thrashes Thornton and then embraces Masie's brave elder sister.
