Korea. 1950. War is war and hell is hell. No innocents go to hell. You've been assigned to the Mobile Army Surgical Hospital 4077. Just mere miles away from the front lines. Your job, along with the 4077, keep the wounded alive in any meatgrinder surgical means possible until they can be evacuated to a more equipped hospital. 24 hour shifts are normal and sanity has long flown away with the wounded.

The nurses here are the best in the US Army, reporting to Major Margaret "Hot Lips" Houlihan, but don't call her Hot Lips unless you wanna be the subject of a whiny report back to command... odds are... she's been romantic with the general she's reporting you to. Some nurses you might work with or come across: Nurse Abel, Bravo, Charlie, Delta.... yeah... there's a pattern (blame the writers of the show).

Then, there are the doctors. Captain Benjamin 'Hawkeye' Pierce, Captain 'Trapper John' McIntyre, Captain B.J. Honeycutt, Major Frank Burns and Major Charles Winchester, and good ol' Colonel Sherman Potter when the body count is high.

Rounding out the staff are Father John Mulcahy, Corporal Walter 'Radar' O'Reilly and Corporal Maxwell Klinger.
