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!
I have no intention of letting them
 win with their petty little tricks.
.لا نيّة لديّ بالسّماح لهما بالفوز بخدعهما الرّخيصة
No pienso ceder la victoria
ante trampas tan absurdas.
No pienso ceder la victoria
ante jugarretas tan absurdas.
Je ne les laisserai pas gagner
Non intendo lasciarli vincere 
grazie a questi trucchetti da quattro soldi.
Não tenho a menor intenção de
deixá-los vencer com truquezinhos.
Я не собираюсь отдавать победу…
