While Boruto and the others are forced to participate in Ouga’s experiments, Sarada and her team investigate Boruto’s disappearance and discover the existence of a suspicious individual. 
Meanwhile, Boruto is shocked to discover the identity of someone who may be working for Ouga. Just then, a test subject is found dead—killed for reasons that have nothing to do with the experiment.

I don't want my throat cut
in my sleep by an enemy spy.
.لا أريد أن أنحر أثناء نومي من قبل جاسوس عدو
Ich hab nämlich keinen Bock, dass
mich ein feindlicher Spion im Schlaf tötet.
No quiero que me mate un espía
mientras duermo.
No quiero que me mate
un espía mientras duermo.
Non voglio saperne di trovarmi 
con la gola tagliata mentre dormo
Não quero minha garganta cortada,
enquanto durmo, por um espião inimigo.
Не хочу, чтоб шпион врага 
мне во сне горло перерезал.
