Life changes completely when humankind has lost sight of sight. Now, humans have to coexist and find new ways of interacting, building, hunting and staying the same. The challenge still exists, but the reality of human beings changes when a group of twins are born with vision and have different visions of the world.
The world the series creates is a fascinating thought experiment about how a society built by a blind population would function. Unfortunately, the story hasn't caught up to the ambition of the production design in the first few episodes.
