Mark Pelton's young wife, Laura, is a drug addicted kleptomaniac. In her delirium she writes her father, John Calvert, accusing her husband of cruelly wrecking her life, then commits suicide. Calvert, knowing the truth, puts the letter aside. Ten years pass and Calvert hopes his niece Pauline will pair with Mark, but she has fallen under the charms of fortune hunter Elmer Danby and plans to elope with him. When Calvert dies, he leaves his estate jointly to Pauline and Mark, provided they marry. If one refuses, he or she forfeits all to the other. Pauline, having found the letter at first announces her engagement to Danby, forfeiting her rights but when he is exposed as a grabber and she learns the truth about Mark they wed.
