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!
but normal civilians can also enter as long 
as they pay an incredibly high entry fee.
لكنّ المواطنين العاديّين بإمكانهم المشاركة 
.ما داموا سيدفعون رسم دخول مرتفع جدًّا
Aber auch normale Bürger können
gegen eine exorbitante Gebühr teilnehmen.
pero si pagan la altísima cuota,
la gente de la calle puede jugar.

mais n’importe qui peut jouer
s’il paie les frais d’inscription.
ma anche dei normali cittadini possono gareggiare
 versando un'astronomica quota di partecipazione.
mas civis normais também podem participar,
desde que paguem uma inscrição caríssima.
но за кругленький взнос
допускают и любого желающего поиграть.
