The Splendid Sin

Although they have a happy marriage, explorer Sir Charles Chatham and his American wife Lady Marion have been unable to have children. After Charles goes to Egypt, his sister Gertrude and her sweetheart Stephen Hartley, an American consulate attaché, take refuge from a storm in a deserted tower. Frightened, Gertrude yields to Stephen's advances. Although he intends to marry Gertrude, Stephen is suddenly called to deliver supplies to starving women and children in Russia. Marion takes pregnant Gertrude away to have her child, and notifies Stephen, but because he is shot during Bolshevik rioting, he returns too late to marry Gertrude, who dies after giving birth. To honor Gertrude's dying request and provide Charles with a much-desired child, Marion telegraphs Charles that the baby is theirs. However, when he returns, his mother, who wants the estate for her son George, tells Charles that Hartley is the father. To stop Charles from shooting Hartley, Marion confesses the truth, whereupon Charles adopts the baby.
