Plot

In 1959, student Lucinda Embry (Lara Robinson) hears whispers as she stares at the sun. When her class is chosen to contribute to the school's time capsule, each child is asked to draw what they believe the future will look like. Lucinda writes a page of seemingly random numbers and adds it to her elementary school's time capsule, which is set to be opened in 50 years. Lucinda's teacher calls for the pupils to finish but Lucinda continues before her teacher takes it off her desk unfinished. Lucinda then goes missing after the time capsule is dedicated, and is found by her teacher, Mrs. Taylor (Danielle Carter), in a utility closet scratching numbers into the door with her fingernails bleeding.
