Desc: The Shadows of a Great City: Directed by Herbert Blaché. With Thomas Jefferson, Adelaide Thurston. A young profligate son of a wealthy merchant falls in love with the daughter of an inventor, who has devoted the best years of his life to perfecting the machinery of his employer's plants. After an accident has caused the death of the inventor, the merchant, none too scrupulous, lays claim to an unpatented invention. Not aware of his father's acts, the merchant's son is courting the inventor's daughter, but parental opposition is interposed. Offering his son a half interest in his business if he will renounce his love for the girl, the father is dumbfounded when his son refuses and decides he wants the girl more than the money. Ordered from home, the son secures a job as stevedore on the docks. The foreman takes a dislike to the boy and tries to browbeat him. After a quarrel, the boy accidentally pushes the foreman into the river, runs away and tells his sweetheart that he has committed murder. Detectives pursuing him, arrest and bring him to headquarters, where he is sentenced to Blackwell's Island. During his sojourn on Blackwell's Island, he learns that the man he is supposed to have murdered is alive, and, enraged at the injustice of his sentence, he breaks jail. In the meantime his young sweetheart has also discovered his innocence through a friendly attaché of the Governor's office, and with his assistance dashes to Albany, where the Governor is persuaded to issue a pardon for her young hero. The next and last scene discloses the happy couple in their own little home.
