The Prima Donna's Special (1917)

Helen, station agent and telegraph operator at Lone Point, is in despair over a broken sounder when Morley, who has dropped off a passing freight, offers to fix it for her. Recognizing in him a man whose skill points back to happier days, Helen encourages him to tell her his story, promising to get him the position of relief operator if he cares to accept it. Morley's story takes him back several years to the time when he gave up his position as an operator following the death of his wife. He has never seen his little daughter since turning her over to the care of a rich brother.
