Synopsis
In a desolate landscape, four high school girls wearing their uniforms walk together without speaking. They were sent 6,000 years into the future from their original era as a final attempt to escape humanity's inevitable extinction. Back in their world, the same day repeated endlessly until they studied time travel at school, passed a selection test, and were chosen to be transported to this new age. Now, they have no idea what to do next. The only thing they brought is a small, toy-like mobile phone that doesn't work because there is no signal. As they walk, they notice strange birds flying overhead and spot a river in the distance with dirty water. Eventually, one of the girls discovers an abandoned house and reads the name carved into its gate.
