Long before M*A*S*H, there was Battle Circus. Made during the Korean War, this tribute to the indomitable human spirit takes an authentic, almost documentary-like look at the nurses and doctors who operated in the battlefront Mobile Army Surgical Hospitals. Major Jed Webbe (Humphrey Bogart) is a brilliant, hard-bitten Army surgeon with a weakness for women and strong liquor. Fresh from the states arrives Lt. Ruth McCara (June Allyson), a naive young nurse ready to save the world. The story of their love and heroism, told against the grimly realistic background of pounding artillery and deadly ambushes, forms the core of the film.

The title Battle Circus comes from the way the mobile field units can strike their tents, move to a new battle area, then set them up again like circus roustabouts in nothing flat. And, like circus daredevils, these heroes risk life and death on a daily basis.
