A story that gives us a glimpse into the future: Josiane and René are children of the generation "50/50," their lives split between reality and virtual reality. And they will be the first to enter this alternate universe completely—and permanently. Through their eyes, and their adventures, we discover a new world where everything is possible, simply because mankind wished it. A world where time and fear no longer exist, and where we will have to learn once more how to live.
