Imagine if an earthquake as powerful as magnitude 8.0 struck Tokyo, the
capital city of Japan, today… Who would we think about and what should we
do at that moment? This is a tremendous human drama that portrays the
connections and human bonds in the most extreme situations.

13-year-old Mirai and her 8-year-old brother, Yuki are left away from home
when the cataststrophically large quake has hit Tokyo…
Most of the mobile phones are dead. There is no clue as to whether their
parents are safe.

The only thing that Mirai is sure of is that she remains with her brother
Yuki, and Mari, whom she just met. She also knows that the three of them
must continue walking through the devastated city of Tokyo to make their way
home.

On their way, the three face numerous struggles, while receiving the
kindness and help of others. It is through this journey that Mirai realizes
what is really important to her, what it is she must protect, and she begins
to understand the meaning of life. What could it be that awaits them
at the end of this journey?
