When a Canadian research photographer is killed, leaving behind a photo of a boy in an otherwise empty room, paranormal investigative scientist, Hashimoto, and his team investigate the scene. Armed with a newly invented material they capture the ghost: an unidentified 13-year old boy. Who is this ghost? Why does it kill people? As they seal off the room and monitor the captured spirit, they soon learn that even though its energy can be visibly seen, humans are unable to hear it. In an effort to learn the ghosts past, Hashimotos team enlists the help of special agent Ye, gifted with extraordinary eyesight and ability to lip-read. As Ye gets closer to solving the riddle of the boys past, he learns the horrifying truth of the boys death. Fearing that the ghost child is dangerous, the team decides to isolate the ghost but in doing so they unknowingly unleash a mysterious force, a much more powerful and ferocious energy to which the boy somehow seems connected.
