An easy-going bumbling Colonel commands a military hospital, the 1066th. A self-serving martinet second-in-command tries to use military regulations to tyrannize over the hospital staff. A fun-loving conniver wants to give the hospital staffers a chance to enjoy the company of the hospital's nurses while the second-in-command tries to thwart him. If Jack Lemmon and his friends had been doctors and officers, instead of enlisted personnel, the general resemblance to MASH would have been complete. When Richard Hooker's novel MASH was turned into a TV series (after passing through the movies), the writers must have been familiar with this movie. Curiouser and curiouser.
