John Worth, a rich old banker, disinherits his son, Robert, for marrying against his wishes. The boy gets a position as chauffeur with a taxicab company and the next day the father, finding that his car is out of order, calls a taxi and by chance Robert is sent to answer the call. Robert decides to kidnap his father and hold him for ransom. With the aid of two hired thugs he imprisons the old man in a lonely, deserted shack down by the river. He then slips a note under the door reading, “Write your check for a thousand dollars, or we will blow the place up tonight.” The father tries to escape through a window but he is too large for the opening and gets wedged in and can’t get either out or back into the room. Robert tells his wife of his plan and arranges for her to rescue his father. She does and the old man rewards her with a thousand dollars. He grows very fond of the girl and questions her. She tells him she is married, opens the door and Robert comes in. The father is thunder struck for a moment, but finally collects himself and starts to denounce the boy. The girl intercedes and through fondness for the girl the old man relents and all ends happily.
