March 11th, 2011, a huge earthquake followed by a giant tsunami strikes the coastal regions of Tohoku in Japan. Starting in the district of Taro, where an old lady and her sister reflect on their fear of the deadly wave that has already struck before in 1896 and 1933, the two directors drive south along the coast. Listening to the inhabitants, they wonder why people continue to live in these dangerous regions, knowing that disaster can hit without warning.
