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!
We holed up in the mountains and endured 
rigorous training just for this day.
اعتكفنا في الجبال وتحمّلنا تدريبات 
.صارمة من أجل هذا اليوم
Wir haben für diesen Tag
hart in den Bergen trainiert.
Nos entrenamos a conciencia
en las montañas, con sangre y sudor.
Nos hemos entrenado a conciencia
en las montañas, con sangre y sudor.
On s’est isolés en montagne
Ci siamo rifugiati tra i monti e versato lacrime
 e sangue allenandoci in vista di questo giorno.
Nos enfurnamos nas montanhas e passamos
por treinamentos rigorosos para este dia.
Ради этого дня мы уходили глубоко в горы
и тренировались там, не жалея себя!
