A child sitting with a psychotherapist (Colm Feore), hypnotized by the sound of his voice and the metronome he uses to put patients under.

Not saying this trailer is particularly scary, but the concept is killer and it is most certainly chilling.

Jackson Robert Scott of the “It” remake has the title role. Taylor Schilling and Brittany Allen also star in “The Prodigy,” which opens Feb. 8.
