Yuta goes to a place he used to visit with his father and is transported back in time. When he comes back to the present, a miracle occurs to the former children of the village.

Yuuta is a 12 year old boy, who lost his father in the accident one year ago. For the summer vacation, he visited a deserted dam deep in the mountains, where he had a good time with his father. Due to a thunder storm, he slipped on the ground, lost consciousness and woke up 30 years before.
