Knowing HD streaming trailer

In 1958, as part of the dedication ceremony for a new elementary school, a group of students is asked to draw pictures to be stored in a time capsule. But one of the students, a mysterious girl who seems to hear whispered voices, fills her sheet of paper with rows of apparently random numbers instead.

Fast forward 50 years to the present: A new generation of students examines the contents of the time capsule and the girl’s cryptic message ends up in the hands of young Caleb Myles.
