The secret files called the Zacharis Dossier may cause a war between the East and the West. In order to obtain a painting that is supposed to be the hiding spot for these files, Loid and Fiona enter an underground tennis tournament run by the owner of the painting, Campbell. If they win, the art piece they're after will be presented. Loid and Fiona enter as a married couple and play various skilled players including pro players!
Any "vermin" that sneak in are
 exterminated without fail.
.إنّ كلّ "حشرة" تتسلّل إلى هناك ستُباد بكلّ تأكيد
Bisher haben sie alle eliminiert,
die sich reinschleichen wollten.
Los ladrones que entraron
desaparecieron sin dejar rastro.
Los cacos que han entrado
se han esfumado sin dejar rastro.
et d’exécuter tous ceux
qui tentent de s’en approcher.
Qualunque "ratto" provasse a entrare,
verrebbe eliminato.
Qualquer verme que consiga se
esgueirar é exterminado sem falta.
Они устраняют всех крыс,
что сунули нос куда не следовало.
