Potter is upset when General Waldo Kent informs him that people in the 4077th are complaining about his leadership. Potter returns to camp and discovers that the complaints are coming from a Corporal (actually Lieutenant) Benson, who had been sent by a disturbed Colonel Frank Webster, who had been wounded some months earlier... and probably wanted payback for being made to wait until the real casualties were treated.
The 4077th Mobile Army Surgical Hospital is stuck in the middle of the Korean war. With little help from the circumstances they find themselves in, they are forced to make their own fun. Fond of practical jokes and revenge, the doctors, nurses, administrators, and soldiers often find ways of making wartime life bearable.
