Against Frank's objections, Hawkeye and Trapper treat a young, shell-shocked GI with hysterical paralysis while Henry searches for a possibly rabid dog that bit Radar.

While Radar tries to stop the camp from being shelled by their own artillery, Frank finds a wounded enemy soldier wired to explode, Margaret and Trapper get stuck in a supply shed and Henry and Father Mulcahy get blown up in the latrine.
