The Big Noise(1928)

John Stoval, a guard in a New York subway, thinks that Philip Hurd, who owns a concession at Coney Island, would make a good husband for his daughter Sophie. Sophie, however, has her sights set on Bill Hedges, the son of a wealthy farmer in upstate New York. Her father arranges for her to marry Hurd in exchange for a 25% interest in the concession, but matters come to a halt when John slips and falls off a subway platform and is injured.
