A young archaeologist has found herself in a tunnel where she is rapidly aging. To avoid turning to dust, she must decipher the laws of the temporal anomaly that is stealing her life—and she only has hours to do it.

SYNOPSIS:

A 21-year-old girl found an abandoned, unknown tunnel and went inside. Ahead, she encountered a 105-year-old woman standing motionless. The woman told the girl that she was her future self and that she must not turn back. If she were to go back, she would instantly become 105 years old and aged, because a temporal anomaly existed within the tunnel. Therefore, the only way was forward.

The further they walked, the younger the old woman became, and the older the girl grew. When the girl became frightened, the old woman explained that once the girl reached 105 years old and the old woman became 21, the tunnel would end, and they would step into the light. And in that world, she would become young again, returning to the age of 21.

But the old woman had deceived her. When the girl reached 105 and the woman became 21, the aged girl stopped and could no longer move. The woman walked on, exited the tunnel into the light, and began to live in the girl's world, taking her place. The old, 105-year-old girl was left standing motionless in the tunnel. Twenty-one years later, she heard footsteps approaching… it was another 21-year-old girl.
