IN THE SWITCH TOWER stars Walter Edwards (who also directed) as Bill Wharton, a middle-aged alcoholic who was once a leading engineer with a railroad. Wharton is estranged from his son Joel (Frank Borzage), who now works as an executive with the railroad, but Frank does send him money through Bill's longtime friend, Louis Hall (Robert Hall).
