Little Oliver feels different and lonely. He has not spoken since he was born and communicated with the world using a smartphone and a tablet. One day, via a mysterious application, someone from another world contacts him, offering friendship. The boy is happy that he has found a true friend, not suspecting that he has just let a creature with a dark soul into our world. Once Oliver's parents realize what is happening, the gates to the other world will be open, and closing them will require a terrible sacrifice.
