A Stormy Knight (1917)

While relaxing in his cabin one stormy night, John Winton, a rising young businessman who has successfully resisted the institution of marriage, is interrupted by cries for help. Opening his door, he finds a soaking wet, pretty girl, who pleads with him to come to her aid. She guides him to a swamp where a man is lying insensible. John carries the man to his bungalow and goes for a doctor. On his return, both have disappeared. John, his curiosity thoroughly aroused, follows the only clue that has been left to him, a glove that is lying on the cabin floor. After a series of mysterious encounters in which the girl is involved, John marries her without knowing who or what she is. Then it is revealed that the whole mystery has been a scheme contrived by John's father to marry his son off by employing the romance of mystery.
