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!
Eventually, you won't have to make 
excuses like that, Twilight.
لن تضطرّ للتّفكير في أعذار كهذه 
.في نهاية المطاف أيّها الشّفق
Früher oder später werden derlei Ausreden
nicht mehr nötig sein, Twilight.
Presto non avrai più bisogno
 di accampare simili scuse, signore.
Logo não vai mais precisar
criar essas desculpas, Twilight...
