The end.
It is an bank robbery that actually happened in Japan of 1979 . The criminal was shot dead.
The story of sex is a creation.
It is true that the female banker became naked.
Yea - and they all just return to work the very next banking day after their humiliating debauchery. Now that the hot lead girl has been raped and sodomized repeatedly by the robber and her fellow "coerced" male employees,(yet "strangely" they looked pretty into it), she now has an untraumatized forgiving attitude. The older males nod their paternal approval as she forgives the kow-towing young pup in front of her - as all good submissive Japanese girls should. The Japanese are apparently total freaks! I like it.
