Marie was seriously injured in an accident and was carried to hospital.
A lot of her internal organs were damaged, and she was unconscious.
It was clear that conventional treatment would not save her life.
However, her father did not give up. He planned to use a newly developed automated medical capsule which was able to slowly restore the patient’s cells while keeping him in a hibernated state.

The treatment procedure takes a very long time, so when the patient wakes up, there will not be any people he knew around, and adaptation to new life will probably be difficult. International relations were degrading and war could break out any moment.
There was much hesitation about putting Marie to sleep for a very long time under such conditions, but, finally the decision was made, and she was put into the capsule.

A catastrophic war broke out while Marie was being treated, and the human race stepped on the road of self-destruction.
