Jack, ever since childhood, has been the twins' hero. The years pass. Jack is as devoted as ever to the two beautiful young girls, but has given no sign that he cares for one more than for the other. The Civil War breaks out and Jack marches away. Each of the twins has come to love the young volunteer, but keeps her secret from her sister. One night Madeline wakes to see Marion standing by the window, looking at Jack's picture in the moonlight. She determines to give up Jack. Marion, however, has guessed Madeline's feelings for their "hero," and has made up her mind that she will not stand in the way of Madeline's happiness. The next day each of the twins writes to Jack. Marion's note tells him that Madeline is waiting for him. And Madeline's missive begs him to be careful of himself for Marion's sake. The letters never are posted. For word comes that day that Jack has been killed in battle.
