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!
It's only a matter of time before 
the painting's owner, Campbell,
إنّها مسألة وقت فحسب أن يُدرك 
مالك اللّوحة كامبل
Es ist nur eine Frage der Zeit,
bis Campbell
Es cuestión de tiempo que Campbell
Es cuestión de tiempo que Campbell
Ce n’est qu’une question de temps
È solo questione di tempo 
prima che Campbell o il governo dell'Est
É só questão de tempo até
Campbell, o dono da pintura,
Боюсь, скоро это перестанет быть тайной,
и восточники узнают о картине.
