Father Steps Out(1941)

Story concerns railroad tycoon J.B. Matthews (Jed Prouty) taking over a rival line, being sent on an R&R vacation by his doctor, falling off his private train-car and landing in a hobo jungle occupied by Faylen and Hall, and being cured of all his ills, while reporter Jimmy Dugan (Frank Albertson) poses as a doctor in order to get an exclusive story about the railroad takeover.
