Gates that connect our reality with other realities. Gates that one day were opened by accident by a group of friends-students. Now, they have a hard time finding each other again in the labyrinth of parallel worlds. Barely escaping one deadly predicament, they land in a new trap—a world that is terribly similar to Earth.

And if the limit of what is possible has already been exhausted—then the people of Earth will have to accomplish the impossible!
