Crossover with M*A*S*H. Premise: This story is set shortly after Colonel Potter and BJ's arrival in late February, 1952. All seems well, after Potter's birthday party and Radar's gift of Sophie; but under the surface, the tragedy of Henry Blake's death eats at them all. Potter's past in World War One and Missouri comes back at him in the form of Nick Knight, seeking that thing he always seeks-and as always, finding trouble from both his world and that of the 4077th.
