Two American G.I.s visiting Tokyo find themselves mixed up with espionage, a pretty flight attendant, a mad scientist, geisha girls, and a goofy magician-hypnotist and his white rabbits.

Returning from wartime China, Keiichi reunites with his mother Inako and adopted sister Tomi. He becomes drawn to Tomi’s beauty, and his mother appears supportive. But Keiichi soon meets Tsuneko, a former wartime nurse who has borne his child. Faced with a summons to stand trial for wartime atrocities, he entrusts Tomi and his son to Inako, then voluntarily turns himself in—believing he must answer not just to Japan, but to the world’s conscience.
