The Days: episodes, trailer and everything we know about this historical drama

This new series, which is premiering on Netflix, tells the story of the 2011 Fukushima Daiichi disaster in Japan. The show is a Japanese production, but it is going to be available everywhere Netflix is available as a streaming option, making it an interesting addition to the summer TV slate.
