The Dawn of a Tomorrow (1915)

A young girl who lives in the London slums is in love with a cunning thief and persuades him to give up his life of crime. Meanwhile, an eccentric millionaire who has been diagnosed with an incurable dementia becomes so despondent that he decides to commit suicide. He disguises himself as a vagrant and wanders into the slums. As he tries to find the courage to kill himself, the young girl encounters him and rationalizes him out of his cowardly act. Her genuine sweetness and strong faith affect him to such an extent, that he begins to believe recovery is possible. Now the girl's sweetheart has been falsely accused of murder, and only the millionaire's licentious nephew can give him an alibi. The girl pleads with the nephew to help prove her sweetheart's innocence. He refuses and tries to take advantage of her. The millionaire arrives in time and shames his nephew to testify correctly. The millionaire now pledges himself to a life of service and charity, and the girl and her sweetheart are happily reunited.
