Joe Butterfly.

The staff of "Yank" magazine are among the first American troops into Tokyo after the Japanese surrender. Their mission: produce an issue of the magazine...in three days. To accomplish the seeming impossible, they reluctantly enlist the aid of black marketeer and arch-conniver Joe Butterfly, who sets them up in a palatial private mansion, complete with lovely daughter -- strictly against regulations. How much trouble can our heroes talk their way out of?
