Four teenagers dressed in school uniforms silently stroll across the barren landscape. these girls are time travelers who were sent 6000 years into the future from their present where each day is repeated endlessly to avoid human extinction. they received training in time travel and passed an aptitude test before being dispatched to the future as instructed. now, they're unsure of what to do since they have no idea about this new world. the only thing they can bring from their past is a small, toy-like cellphone that doesn't work here. as the girls walk, they notice unusual birds flying in the sky and a discolored river nearby. one girl spots an abandoned house with a name written on its gates.
