A group of high school students is visiting a certain cave on a field trip. A small group of them enters a corridor leading away from the main cave... but one of them, Tomoko, is ultimately left alone. After a few moments, she hears the screams of her classmates from deep inside the cave...
I'm going to live! Only me!
!سوف أعيش! أنا فحسب
Nur ich werde leben. Ich allein!
¡Voy a vivir! ¡Solo yo!
¡Voy a vivir! ¡Solo yo!
Je sauverai seulement ma pomme !
Io vivrò! Solo io!
Eu vou salvar a minha a pele. 
Somente a minha!
