Here's why:
* Little girl dies in a car crash: The main child character, Cole Sear, sees dead people, including his friend, a little girl who died in a car accident.
* Dance recital: The girl, Vincent Gray, was on her way home from a dance recital when the accident happened.
* Leaves clues for her father: Cole helps the girl's father, Malcolm Crowe, understand what happened to her and why she is still lingering.
While the movie primarily focuses on Cole and his ability to see ghosts, Vincent Gray's story is a key part of the plot, and it revolves around the themes of communication between the living and the dead and finding closure after a traumatic death.
