The Count di Montrone (Monroe Salisbury) is in love with his ward, Mary Drake (Jean Calhoun). But he is quite a bit older than she is, and he believes that she's in love with his cousin, Giorgetto Pisani (Charles West), so he doesn't press his suit. Pisani, however, only wants Mary for her fortune. When the Great War breaks out, the Count heads for the front, while Pisani spends his time gambling in Monte Carlo and getting Mary's brother Oliver (Ray Gallagher) to serve in his place. Ultimately, the rogue runs out of money and steals jewels from the family estate. The Count is there, having been furloughed, and is struck by lightning. Even though Pisani knows that he is alive, he has the Count buried in the family vault so that he can continue to court Mary. The Count wakes up and through superhuman effort, escapes his internment. The ordeal, however, has turned his hair white, and when he returns to Mary, she doesn't recognize him. But when he plays the melody that expressed his love for her, she knows him once again, and they are reunited.
