Before he can pack, the Japanese army, lead unofficially by a bloodthirsty imperial uncle, lays siege to the city. Rabe accepts, as prominent representative of Japans' major European ally, to head the Western ex-pats society's plan to start and run an international zone, like worked in Shangai. Rabe however wants it to save his workers and their close ones, over 200,000, and sacrifices all his personal interests.
